12). Equal Interval - Numeric variable in which differences between values correspond to differences between values correspond to differences in the underlying thing being measured
Ex. 45 - 90 degrees Fahrenheit.

Ranked Order - Numeric variable in which values correspond to the relative position of things measured.
Ex. Ranking of someone in a race (1st, 2nd, 3rd). Officer ranking (1st Lieutenant, 2nd Lieutenant).

Nominal - Variables in which the values are categories.
Ex. Religion, recipes, food types, etc. These types of variables measure the quantities or features of a type of group.

Ratio Scale - Equal-interval variables are measured are measured on this type of scale. It has a absolute zero point, or a complete absence of the variable.
Ex. Temperature of 0.0 , height, etc.

Continuous - Limits the variable ranges, if any value is present.

Ex. Number of people in a theater, restaurant, play, etc.

15). The flow the central tendency indicates that each individual clocked in under a distinctive speed within a 35 -mph range. Most of the ratings prove that a vast amount of people fell into speeds between 20 and 35 while a few went way over the speed limit.

Speed Score | Frequency | Percentage | 15 | 1 | | Speed Score | Frequency | Percentage | 15 | 1 | 2.5 | 20 | 1 | 2.5 | 23 | 1 | 2.5 | 24 | 1 | 2.5 | 27 | 1 | 2.5 | 28 | 1 | 2.5 | 30 | 3 | 7.5 | 31 | 3 | 7.5 | 32 | 3 | 7.5 | 33 | 2 | 5.0 | 34 | 4 | 10.0 | 35 | 2 | 5.0 | 36 | 5 | 12.5 | 37 | 2 | 5.0 | 38 | 1 | 2.5 | 40 | 3 | 7.5 | 42 | 1 | 2.5 | 45 | 1 | 2.5 | 46 | 1 | 2.5 | 52 | 2 | 5.0 | | | | | | | | | |

19). A bimodal distribution has two fairly equal points.
Ex. If the average age of college students in the US consisted of 100 people, and out of 100 students, 35 of them were 18, the other 35 would be 30, and the remaining value rests between the range of 19 and 29. On a graph, it would resemble two humps: one would depict the average age of 18 and the other hump would show the average age being 30 as well.
Approximately rectangular distribution is the value of the frequency is about the same.
Ex. Tossing a die and rolling the same number consecutively (i.e. getting a 2 and on the next roll, getting a 2 again).

Positively skewed distribution is a type of graph that is not symmetrical by any means. There are negatively skewed distributions that curve to the left while positively skewed ones fall on the right side.
Ex. People who are enriched with money starting from the wealthiest family (left) to the poorest family (right).

20). This graph exemplifies how it seems like a deliberate attempt to undermine how the population growth of immigrants is misconstrued deeply. Some people out there are too closely and dependently biased on their government, or simply captivated by the primitive feeling of fear to restrict their initiative to investigate the phenomenon or grasp what's occurring. The frequency of immigration has increased dramatically over the past 30 + years, especially after the border control being implemented to restrict illegal immigrants from crossing over.

21).Think of a frequency table as a depiction of the percentage for each option or answer in this case. Much like a pie chart or the information tab of a cereal box, a frequency table's purpose is to tell you what the total is made up of and how much of each ingredient is there. There is three answers that w are given and to determine each answer's percentage you need to do a few steps: First, like finding the mode of a set of data you want to count up the results and once you've done that, separate them into groups based on each option. You then count up the total for each and divide by the sum or total of all the answers. This gives you the percentage or frequency that the particular answer has in the data set. So, to summarize, a frequency table displays the percentage of the total each portion represents to put into perspective what each portion really represents.

22).A frequency table shows how each portion compares to the collective sum. In this table, female and male responses to and for intimate aggression are being compared to one another to shed light on the subject. It may look confusing but it is quite simple, to form a frequency table you need a data set that has similarities and differences. Akin to a Venn diagram, a frequency table pairs similar pieces of information together and separates the pieces that do not match to another group in which they do. The results in this table show that women have more control motives than males for perpetrators but for comparisons they are roughly equal to each other.

Hippo Problem, Math and Logic

...Jory Roberts Math and Logic Tuesday and Thursday, 2 p.m. The hippo problem The hippo problem is a difficult problem to solve. It took me quite some time to solve this problem and I had to employ multiple heuristics in order to solve this problem. In the paper that follows I hope to not only demonstrate how I personally came to the conclusion of solving this problem, but also to help someone else solve a similar problem in the future. The steps in which I took to solve the hippo problem were many, and like any good problem, there is a first step that one must take in order to solve the problem. The first step I took is to re state the problem. "Jill is the chief hippo caretaker at the wild animal park in san Diego, California. She has just arrived at the cargo dock in the downtown harbor to pick up four hippos. In order to complete the paperwork, she needs to weigh each hippo. The only scale available is a cargo scale that starts at 300 Kg. More than one of the hippos weights. Jill is puzzled for a few moments, then gets an idea of weighing them in pairs, thinking that if she gets the weight of each pair, she can figure out the weights of the individual hippos. The weights for the first five pairs are 312, 356, 378, 444, 466. As she weighs the last pair the scale breaks. What was the weight of the last pair? and what are the weights of the individual hippos". That is the problem in its entirety. As you can see, it is quite a complex problem. In the paragraphs...

Math Problem Set

...1. N/A 2. People living near the ocean experience the ocean’s moderating influence on the climate because the ocean absorbs heat when the air is warm and releases heat when the air is cool.  Because it is a fluid, the ocean diffuses the effects of a temperature change for great distances via vertical mixing and convective movements. The solid land cannot, so the sun's heat penetrates only the thin, upper crust.  One consequence of the ocean's ability to absorb more heat is that when an area of ocean becomes warmer or cooler than usual, it takes much longer for that area to revert to "normal" than it would for a land area. This also explains why "maritime" climates tend to be less extreme than "continental" ones, with smaller day-night and winter-summer differences.  3. Clouds act as an insulator to trap in the heat. When there are no clouds, the heat can leave the earth more quickly. 4. An ordinary fan does not cool the air directly. It actually warms the air slightly, because the motor used to power the fan will exhaust some heat into the air, and the increase in average kinetic energy of the air molecules caused by the fan blades pushing them means the air temperature increases slightly. The reason for using the fan is that it keeps air moving. The human body warms the air immediately around it, assuming the air is initially cooler than the body. If that warmed air stays in contact with the body, then the body will lose little further heat after the air...

Pentium Flaw

...a lot of math. The flaw was discovered first by Intel but they did not act on the problem, but a professor from Lynchburg College, Virginia called Dr. Thomas R. Nicely discovered the problem around June 1994 he was the one that noticed it in two sets of numbers and did some tests on 486 and Pentium-based computers, Dr. Nicely was certain that the error is caused by the Pentium Processor. Dr. Nicely then contacts Intel Technical Support on October 24, 1994 Intel technical support then duplicates the problem and confirms it, but it was not reported before. Later the Intel person he had contacted admitted that Intel had been aware of the problem since May 1994, when the flaw was discovered by Tom Kraljevic. When Intel first knew about the problem they decided not to tell anyone, thinking that the flaw would hardly affect anyone and that it was just a commonplace for a complex microprocessor to have a few bugs. Then, when it was forced to acknowledge the problem, Intel pushed it away again and dismissed the chances of it causing problems for the average user. In my opinion, Intel was acting very unprofessional when they knew about the problems and did nothing to fix the problem. I think that Intel was just trying to save money with them thinking “maybe if we don’t fix it and just let it hurt a couple of people, the consumer will have to try to fix it themselves and keep buying parts from us”. But instead it was the other way around the people found out about the problem with the...

Strategies for Math and Note Taking

...SDS101 9 November 2015 Strategies for Math and Note Taking I believe Math is learned by doing the problems and doing the homework. The problems help you learn the formulas you need to know, to help with problem solving. I have learned from my own personal experience that you must keep up with the Instructor: attend class, read the text and do homework every day. Falling a day behind puts you at a disadvantage. Falling a week behind puts you in deep trouble. I have found that college Math is much different than high school math. College math class meets less often and covers material at about twice the pace than a High School course does. You are expected to understand new material much more quickly. So it is very important that if there is something you don’t understand, you should take responsibility for studying, recognizing what you do and don't know, and knowing how to get your Instructor to help you with what you don't know. When it comes to Math testing, it can be very stressful, as with taking any test. Some of the strategies, I have tried, is to look for the problems I definitely know how to do right away, and those that I have to think about. I start with the problems that I know for sure I can do. Then I try the problems I think I can figure out, then I finally try the problems I’m least sure about. I try to make sure I read the questions carefully, and do all parts of each problem. If I find that I am stuck on a problem, I don’t waste too much time and I move...

Math

...Diana Garza 1-16-12 Reflection The ideas Stein presents on problem saving and just math in general are that everyone has a different way of saving their own math problems. For explains when you’re doing a math problem you submit all kinds of different numbers into a data or formula till something works or maybe it’s impossible to come up with a solution. For math in general he talks about how math is so big and its due in large measure to the wide variety of situations how it can sit for a long time without being unexamined. Waiting for someone comes along to find a totally unexpected use for it. Just like has work he couldn’t figure it out and someone else found a use for it and now everyone uses it for their banking account. For myself this made me think about how math isn’t always going to have a solution. To any math problem I come across have to come with a clear mind and ready to understand it carefully. If I don’t understand or having hard time taking a small break will help a lot. The guidelines for problem solving will help me a lot to take it step by step instead of trying to do it all at once. Just like the introduction said the impossible takes forever. The things that surprised me are that I didn’t realize how much math can be used in music and how someone who was trying to find something else came to the discovery that he find toe.

According to Cook “ Project failure occurs when a project is significantly over budget, takes must longer than estimated timeline, or has to be terminated because of so many problems have occurred that proceeding is no longer judged to be viable.” With Memorial Health System failed implementation of a CPOE system they had many problems including an over budgeted project, Lack of belief in project, Insufficient leadership support, Failure to respect uncertainty, Failure to anticipate short-term disruptions, and initiative undernourishment. In this paper we will discuss all six of these problems along with give possible solutions to each of them. Failure to respect uncertainty: When the system was finally implemented it was had a lot of bugs in the system. They implemented the system at all of facilities. Because of this as well as a few other issues such as lack of training the system was taken offline and they continued with the old system. The solution to this problem would have been to implement the system in one location instead of the entire hospital. This place can be used as the test facility in which you can do two things. One you can work all the bugs out and the other would be to use it as a training facility where you can send employees to get training on a system that is up and running. This will...

Jones Electric Memo

...SUMMARY Recently there is something wrong with the performance of our company and I think what we should do is to upgrade the office furnitures. Because more and more of our employees claimed about the poor working condition. We can reduce the surgery fee and the sick days from the employees after the upgrade. Therefore, we can increase our productivities a lot. THE PROBLEM 1 Increase health problem- More of our employees are having health problems because of the uncomfortable furnitures. 2 Sick days increase-Because of their health problem, employees asked for the extra vacation day. 3 Surgery fee increased- Three employees had to have carpal tunnel surgery, and another had back surgery 4 Insurance fee increase- The insurance carrier was threatening to raise its premiums. 4 Productivities reduce- The day-to-day productivity of the office reduced THE REASON The problem came up from last year. If we don’t care about the problem, it will cost us a lot. For example , we already have three employees need to do carpal tunnel surgery . Cost of surgery and rehabilitation is in the range of $5,000 to $10,000 (data from :http://www.mycarpaltunnel.com/surgery-release-carpal-tunnel.shtml).And we have one employee need to have back surgery. According to the data from www.ehow.com. This procedure costs an average of $12,000to$15,000. So far the maximum cost is approximately $45000. And if we ignore that, the number of employees who need surgery would double in the next...

Buenavista Plywood

...Buenavista Plywood Corporation The Problem The problem confronting Mr. Antonio Garcia, the Plant Superintendent of Buenavista Plywood Corporation is how to deal with the absentee rates of the employees from Bohol such that the production of the plant will operate at capacity, with adequate workforce and the interests of the company and employees be served. Objectives More specifically, the problem resolves itself into the following objectives which Mr. Garcia has to achieve in the course of action he has to take: 1. To maintain a stable and reliable workforce; 2. To protect the company’s reputation by avoiding confrontation with formal union groups; 3. To address production problems and costs; 4.

Situational Analysis The Buenavista Plywood Corporation was organized in Cagayan de Oro City in 1950 by the Santiago Family. Don Jose Santiago, the present head of the family, was well qualified to carry the traditions of this prominent family. The Santiagos have been involved in politics in nearby Bohol, the ancestral home. They had been pioneering industrialists in the plywood business. Don Jose had been an early advocate of local processing of lumber as opposed to the shipping of log abroad. VISTAWOOD, the trademark chosen for their plywood, was one of the first export plywood production in the Philippines. Late in the...
