20 out of 20 points | | | A placebo can always be implemented in an experiment, and given to the control group.Answer | | | | | Selected Answer: | b. False | Correct Answer: | b. False | Answer Feedback: | While it IS true that when used, a placebo is given to the CONTROL group, it is NOT true that it can ALWAYS be used. If any part of a true/false question is false, the answer is FALSE. There is an example of a experiment in the textbook where a placebo could not have been used. It is on page 7 of Ch. 2. It is talking about "The Portacaval Shunt". Here, we see that a placebo cannot be used, as we cannot trick someone into thinking that they have had surgery performed on them. With surgery, the researcher cannot, for example, give someone something like a sugar pill for a placebo. | | | | | * Question 2

Quiz 2
Quiz 2 | | | | | | | | | | | | Instructions | | | * Question 1
16.67 out of 16.67 points | | | Crowding on a histogram is determined by theAnswer | | | | | Selected Answer: | c. height of a block. | Correct Answer: | c. height of a block. | Answer Feedback: | You are correct!! The crowdedness of a block is defined as: percentage per (one) horizontal unit. So, we are trying to find which block has the greatest percentage contained in it, when we hold the width to one. Since percentage is width times height, and we are making the width one, then the block with the greatest percentage is the block with the greatest height.
(Ch. 3, p. 40 in the box at the top of the page.) | | | | | * Question 2
16.67 out of 16.67 points | | | For the following table, make the histogram, and find the height of the block from 15 to 30. Income Level Percent 0 - 10 20 10 - 15 15 15 - 30 25 30 - 55 40Answer | | | | | Selected Answer: | d. 1.67 | Correct Answer: | d. 1.67 | Answer Feedback: | You are correct!
To find the height, take the percent and divide it by the width. For this interval, the width is 30-15=15. So, take 25/15=1.6666666, or approximately 1.67. | | | | | * Question 3
16.67 out of 16.67 points | | | For histograms in the density scale, the unit on the vertical scale is percent.Answer | | | | | Selected Answer: | b. True | Correct Answer: | b. True | Answer Feedback: | You are correct!
Ch. 3, p. 38. | | | | | * Question 4
16.67 out of 16.67 points | | | The areas of the blocks in histograms represent percentages.Answer | | | | | Selected Answer: | a. True | Correct Answer: | a. True | Answer Feedback: | You are correct!
Ch. 3, p. 32. | | | | | * Question 5
16.67 out of 16.67 points | | | Use the following table to make the histogram, then find the percentage below 20. Income Level Percent 0 - 5 15 5 -15 25 15 - 25 30 25 - 50 30Answer | | | | | Selected Answer: | e. 55 | Correct Answer: | e. 55 | Answer Feedback: | You are correct! To find this area, we need to add up the percentages contained in the blocks from 0-5, 5-15, and 15-20. To find what the area is worth from 15-20, we need only realize that 20(the number we care about) lies exactly in the middle of the interval that actually exists, 15-25. So, if the area from 15-25 is 30%, then from 15-20 is half of that, or 15%.
So, add up 15%, 25%, and 15% = 55%. | | | | | * Question 6
16.67 out of 16.67 points | | | This table represents the distribution of 300 families by income in the U.S. in 1974. Class intervals include the left endpoint, but not the right. The histogram should be made such that the Income in thousands of Dollars is the horizontal scale. Income Level Frequency Percent 0-2000 11 3.7 2000-4000 15 5 4000-7000 22 7.3 7000-10000 35 11.7
10000-16000 ______ 12
16000-24000 ______ ______
24000-32000 70 23.3
32000-50000 55 18.3
50000 and over 5 1.7 When drawing this histogram, the height of the block from $7,000 to $10,000 will be:Answer | | | | | Selected Answer: | e. 3.9 | Correct Answer: | e. 3.9 | Answer Feedback: | You are correct!
To find the height, we divide the percent by the width. So, here, we take 11.7/3=3.9.
Note: the width is 3, not 3000, since the income is in thousands of dollars. | | | | |

To find this area, we need to add up the percentages contained in the blocks from 0-5, 5-15, and 15-20. To find what the area is worth from 15-20, we need only realize that 20(the number we care about) lies exactly in the middle of the interval that actually exists, 15-25. So, if the area from 15-25 is 30%, then from 15-20 is half of that, or 15%.

...Java Class MIS 304 is not a class for everyone. Not just any student should take the class. This class is structured to assist students in learning how to program using the Java language. This class does not make a student an expert in the language of Java, but instead gives the student the basic fundamentals needed to have practical use of the language and gives them a solid foundation upon which they can build if they choose to do so. The material covered in the class is adequate. Java can be a complex language to learn, but in MIS 304 one is taught the basics and nothing too detailed or complicated. The resources that are given to the students are very good. I know that the Java book used for the class is one of the best reference materials on Java that is on the market today. The lab facilities and proctors are also great resources. The only problem I feel that exists is that students don’t take advantage of the resources they have available. Students hardly look through their book for answering questions they might have. Also students hardly even bring their books to the lab when doing programs. They sometimes look for proctors to fix their problems instead of fixing it themselves. I think it should be emphasized to students that the proctors are not their to do the programs for them, but to rather help them figure out what is going wrong in their programs. Also it should be emphasized that the book should be with them when working on programs so that if questions or...

...level school by mistake (Rose 141).”The educational system is partially to blame, according to Mike Rose. Many learners will pass through high school having undergone negative elements such as fear, frustration and boredom. Mike Rose did not escape the sour side of the educational system. Rose hadn’t stayed in school for more than two months before getting a blow on his face and having his glasses broken by the English teacher who he referred to as being troubled. This was one way fear was instilled in the students' mind. During the Spanish class with the new tutor, Mr. Montez, he was not able to settle the dispute between Billy and Dweetz which ended up into a fight in the classroom. The physical exercise teacher also had a negative impact in his life. He would make students touch their ankles and spunk them to make men out of them. Therefore, this paper will try and prove that Anyon is right when he says that schools socio-economic class determines the type of instructions students receive. When you have a poor educational system, then the future generation will be poorly equipped with skills. The only way out is to get exceptional teachers who can teach students on how to make hypotheses which is one of the key requirement to survive in any job. On the other hand, the vocational education system makes students more mediocre and poor problem solvers. They are totally unprepared to go out into the world. Such students have a culture of doing anything possible to get by Most...

Social Class

...Social class, which is usually determined by a combination of one’s income, education, and occupation, may be less visible than other types of difference. However, in many countries where individualism is valued, it is common to believe that all people are created equal and that the same opportunities are available to everyone who has the innate talent and is willing to put in the effort. However, this position ignores the challenge of overcoming the social, educational, and networking resources of class origins. For example, the U.S. General Accounting Office reported that suburban school districts spend up to 10 times more on their public school systems than urban districts (U.S. GAO, 1997). This exercise is designed to help you to understand how social class could affect a person’s life experience due to differences in access and resources. Although social class in childhood does not necessarily determine status across one’s life span, it may limit educational and career options. This may make it more difficult for a person to achieve his or her career and personal goals. Of course, individuals within a social class can have very different experiences, due to a variety of factors.

...Name Course Instructor Date Swept Away: Gender and Class Struggle In the 1970’s, Lina Wertmuller introduced herself into the Italian film industry as the first female director to be recognized and acclaimed internationally (Hcl.harvard.edu). The film Swept Away has come to be known as a phenomenon in the Italian film realm with its keen satire and Rabelaisian humor working as one to highlight some issues affecting post-war Italy (Nytimes.com). In the film, Wertmuller reinvents the character types and narrative forms of the mainstream Italian comedy to come up with a rare, radical, and political film that achieves widespread popularity (Hcl.harvard.edu). In the film, she focuses on issues such as class, politics, and gender. However, it is quite obvious that the film brings a commendable job by using gender struggle as a metaphor for class struggle. The audience is introduced to Raffaella, a woman who is vacationing on a yacht. She is disrespectful and often insults the Sicilian crewmen on the yacht. She insists on being taken to an island despite the rough waters at dusk (Hcl.harvard.edu). Gennarino agrees to take her, but a sudden turn of events sees them lost and drifting away to a desert, where they have to fend for themselves and forage for food, something Raffaella is ill-equipped to do (Nytimes.com). The intrusion in which Gennarino decides to leave Raffaella out by herself knowing perfectly that she was not capable of working or foraging for food, so she would have to trade...

Middle Class

...I know I’m dating myself by writing this, but I remember the middle class. I grew up in an automaking town in the 1970s, when it was still possible for a high school graduate — or even a high school dropout — to get a job on an assembly line and earn more money than a high school teacher. “I had this student,” my history teacher once told me, “a real chucklehead. Just refused to study. Dropped out of school, a year or so later, he came back to see me. He pointed out the window at a brand-new Camaro and said, ‘That’s my car.’ Meanwhile, I was driving a beat-up station wagon. I think he was an electrician’s assistant or something. He handed light bulbs to an electrician.” In our neighbors’ driveways, in their living rooms, in their backyards, I saw the evidence of prosperity distributed equally among the social classes: speedboats, Corvette Stingrays, waterbeds, snowmobiles, motorcycles, hunting rifles, RVs, CB radios. I’ve always believed that the ’70s are remembered as the Decade That Taste Forgot because they were a time when people without culture or education had the money to not only indulge their passions, but flaunt them in front of the entire nation. It was an era, to use the title of a 1975 sociological study of a Wisconsin tavern, of blue-collar aristocrats. That all began to change in the 1980s. The recession at the beginning of that decade – America’s first Great Recession – was the beginning of the end for the bourgeois proletariat. Steelworkers showed...

Working Class

...Park Avenue Response When it comes to the topic of the working class, most people in today’s society would agree that the rich people have nothing to worry about financially. Where this statement would become controversial is whether or not the system is rigged by giving more opportunities to advance to the rich. The assumption is the U.S economy seems to be failing the majority of the working class who do not have the luxury of being rich. In the documentary “Park Avenue”, it is said that the rich have more opportunities to advance in today’s society. I agree to this statement, but I think that it is only true because the rich already have the money to do whatever it is that they would like to do. The rich can continuously invest in their money to make it possible to accumulate more money. However, for the working class, hard work is no longer enough to keep up with every day expenses. Many jobs available today are low-wage positions without benefits and no opportunities for advancement. Because of the low paying jobs, 40 hours a week is no longer the average amount of hours a person is working a week. Many people now have a part time job to supplement the income given from a full time job. Even with two jobs, many people still do not have the ability to have an adequate amount of money saved in a savings account. “Education is the key to upward mobility,” is stated by the author.

Social Class

...Social Class Assignment. August 11th 2014 3:21 AM. 1. Discuss and explain PEW’s definition of social class in America and how it pertains to income, society and culture. The definition of social class according to Pew research and based on the results of their survey is the stratification of individuals based on income, education level, financial satisfaction, occupation wealth and prestige. Based on those factors individuals are grouped into levels of socioeconomic class namely: upper class, upper-middle class, lower-middle class, and lower class. For the sake of their survey, Pew research grouped together the individuals in the lower-middle class and lower class into one group. Any observer of American society would quickly note that there are large variations in wealth, material possessions, power and authority, and prestige in our society.  They would also note differences in access to education, healthcare and leisure. Income is one of the biggest measures or indicator of socioeconomic status. In the United States there is inequality in the distribution of income. Those in the upper class aka the elite represent the smallest percentage of the population yet they hold majority of the income. The opposite can be said for their friends at the end of the spectrum, they make us the largest part of the population and have the least amount of the income. According to Leonard Beeghley a household income of roughly $95,000 would be typical of a dual-earner middle class household...

Class Matters

...Stacy Schmauss ANT 210 10/18/2012 Class Matters A class is defined as "A combination of income, education, wealth and occupation." (Ember, Ember, and Peregrine 315) Social status or economic class has shaped society since the beginning of man. Whether it is money, power, or strength, certain people are put into classes that gain them respect. Especially during this time of year when the election is going on, we hear class mentioned all the time. The upper class is the wealthier people in America, the middle class is what can be described as your "Average Joe", and the lower class are those that are struggling to provide for themselves. Class can affect things such as getting jobs, what kind of women or men you will attract, and how you are treated. Whether people want to believe it or not, class is a huge part of how we view people and it always will be. The New York Times came out with a special study about economic class. According to them, "class influences destiny in a society that likes to think of itself as a land of unbounded opportunity." (Scott, and Leonhardt) The article states that class is a powerful force in the life of Americans and places a huge role in shaping us today. Things such as your family name, education, and ethnicity all play huge rolls what class you fall into. In my personal opinion, I would have to say that the article hits the nail right on the head. Class is a widely debated topic and the people in each class play huge rolls in how our country...

Class Inequlaity

...disadvantaged in the contemporary UK. Having the working class as disadvantaged is proven to be right because of many reasons, some say its health reasons, others say its educations or economic downturn etc. there are all sorts of observations which contribute towards why the working class are at a disadvantage in the contemporary UK. One observation as to why the working class are at a disadvantage is education because without having the knowledge you will not be able to achieve much in society. Research has shown that the working class children perform much worse in education than all other social groups at all levels of education. The reason behind this is because just like Hirch’s understanding that the working class are unable to provide for the children because they don’t have the financial advantage so they lack in material resources which puts them to a disadvantage. Also to back this up, the Sutton trust had concluded that people who go to private institutions are more likely to get into a university like Oxbridge because these children and parents are at an advantage economically as they have to pay a large fee to get into the private institution. Also, with education come cultural capital for example because of the parents being able to understand which schools better and understand the league table and such, they will have better knowledge as to where they should send their children to, this gives the middle class a more of an advantage because the children would benefit...

Class Differences

...Explaining class differences On popular explanation of class differences in achievement is that better-off parents can afford to send their children to private schools, which many believe provide a higher standard of education. For example, average class sizes are less than half those in state schools. External Factors Cultural deprivation – Theorists argue that most of us acquire the basic values, attitudes and skills that are needed to educational success through the primary socialisation of the family. The basic ‘cultural equipment’ includes things such as language, self-discipline and reasoning skills. They believe many working-class families fail to socialise their children adequately. There are three main aspects of cultural deprivation: Intellectual development, Language, Attitudes & values Intellectual development –This refers to the development of thinking and reasoning skills such as the ability to solve problems and use ideas and concepts. Cultural deprivation theorists argue that many working-class homes lack the books, educational toys and activities that would stimulate a child’s intellectual development. Douglas (1964) found that working-class pupils scored lower on tests of ability than middle-class pupils. Bernstein (1967) found out that middle-class mothers are more likely to choose toys that encourage thinking and reasoning skills and prepare children for school. Language – Bernstein (1975) identifies differences between working-class and middle-class language...

The Social Class

...The social class now a day will have influence in their vote, but what is most influential is Income, and Aspiration. For instance a rich, upper class person will always vote for the Government that will tax them least, they do have a good income and everything they need, and they care lees for people who have much less. The upper middle class are the one who also objects to taxation, they often pay a lot of tax and resent it being 'wasted' on useless spending. However, many of these same people rely on the Government for their highly paid jobs, so there is a dichotomy here. They will classify spending money on the Health Service, and qualify 'waste' as money spent on anything they themselves don't approve of. Immigration (with no distinction of what kind of immigration they are talking about) is often touted as the basis of all the country's ills, the erroneous assumption being that the Government pays for all illegal immigrants and asylum seekers to live in hotels. They know that it would cost them more of their income to pay for Health Services privately than they pay in tax, but they still aspire to improve their lot. All political parties try to convince the public they have the perfect balance between prudent public spending and reasonable levels of taxation. Will vote for the party that sounds best on the day.
