Variables in Research
In research, variables are any factors in the experiment at hand, whether they are the factors being measured, the factors being changed by the researcher, or the factors which are kept constant in order to ensure consistency in at least one area of the study, which leads to increased reliability of the study (Shermerhorn 2014). These variables which are kept constant throughout the experiment are arguably the most important, but how can something which is never changed make such an impact to the results of any research.
The importance of these unchanged factors, or constant variables, stems from their ability to isolate the independent variable, or the variable which is intentionally changed by the researcher. An example of this would be in the very simple experiment of measuring the bounce of a ball when dropped from different heights. The measured variable in this experiment is the height of the bounce of the ball, the experimenter is interested to see the effect on the rebound height, due to changing the drop height. In this example, the must obvious factor in the experiment which needs to be maintained is the type of ball, if this variable were to be changed, all previous data gathered will become irrelevant, as the results would all be in reference to a different ball, whose rebound heights have no connection to that of the new ball. Therefore, it is plain to see how useful control variables can be when used properly to isolate the variable which will bring about a measured change.

Variables and Research

...This requires research because it is important that we figure out whom and what is responsible for costing the store money. Because it is not information that is easily given up, I must conduct research that begins with my ultimate goal or question, establishes a hypothesis, determines the variables, and figures out the ethical considerations. Research Question The research question that I ask myself when researching the high number of alcohol cost is who is responsible? The next research question I ask myself is How can I determine who is responsible? The final research question is when all of this information is figured out, what can I do to fix it? Hypotheses The hypothesis in my unique organizational example is that I always expect to find that bartenders are most often giving away free drinks in hopes of making more financially from the customers. The background behind my hypotheses comes from many years in the restaurant industry and being shown this to be true often. Unfortunately, when it comes to money, greed comes in to play and proper ethics and morals go out. The reality that this might not be the case is known, but it continues to remain my hypotheses, none the less. Variables The variables in this issue are the different people that work different shifts, the other coworkers that also have access to...

What Are Intervening Variables? How Are They Related to the Concept of Parsimony? Give an Exmple from Piece of Research That Was Discussed in Class or in the Book.

...Intervening variable used in the book are classified into independent and dependent variables. Independent variables are those manipulated by the experimenter. For ex- ample, not allowing rats to have any water for several hours would create an independent variable called hours of deprivation. Dependent variables are those observed by the ex- perimenter. For example, one could observe how much water a rat drinks. Science tries to explain the world by relating independent and dependent vari- ables. Intervening variables are abstract concepts that link independent variables to dependent variables. The principle of parsimony, maintains that researchers should apply the simplest explanation possible to any set of observations. For instance, psychologists try to explain results by using well-accepted theories instead of elaborate new hypotheses. Parsimony prevents psychologists from inventing and pursuing outlandish theories. In the book on page 15 figure 1.3 it shows a direct and an indirect way to relate an independent variable, hours of deprivation, to a dependent variable, rate of bar pressing. The dependent variable is obtained by placing a rat into a small chamber where it can press a bar to obtain drinking water. The experimenter observes the rate (how many presses per minute) at which the rat presses the bar to get water. The direct relationship uses only one arrow to link hours of deprivation to rate of bar pressing....

...Tell when to use a Pearson’s correlation, the possible research hypotheses for this statistical model, and when correlation can be used to test each type of Research Hypothesis (attributive, associative and causal). 1. A Pearson's correlation is used when you want to find a linear relationship between two variables. It can be used in a causal as well as a associativeresearch hypothesis but it can't be used with a attributive RH because it is univariate. 2. Pearson's correlation should be used only when there is a linear relationship between variables. It can be a positive or negative relationship, as long as it is significant. Correlation is used for testing in Within Groups studies. A possible research hypothesis for this statistical model would be that there is a positive linear relationship between variables. Another possible research hypothesis would be that there is a negative linear relationship. If there is no linear relationship between the variables, then we would retain the null hypothesis. 3. Pearson's correlation should be used when there is a significant effect. (p > .05) When there is a relationship between two variables. There can be a positive or negative correlation. It cannot be used when we retain the null hypothesis because then there is no relationship. It can be used if the null is rejected. 4. A Pearson's correlation is used when two quantitative variables are being tested in the RH. This cannot test attributive RH, but can associative and causal....

Research Design

...Chapter 5 RESEARCH DESIGN GENERAL CONCEPT MULTIPLE CHOICE QUESTIONS 1. General Mills conducted research on a "new, improved" version of their cereal, TRIX. Consumer taste tests showed the new version was preferred over the old TRIX, but the new version was a failure when it was introduced. It was noted that the research was flawed in that the new version of TRIX was compared with the old TRIX, a choice that consumers in the marketplace would not have. The correct research should have compared the new TRIX with competitor brands. This example was presented in your text to illustrate: a. poor budgeting for research b. how researchers in large firms are in "silos" and are not open to outside suggestions c. how former research studies often determine the design of present studies d. improper research design e. a case where exploratory research should have been undertaken after the causal research Answer: (d) Difficulty: (Moderate) Page: 114 2. Which of the following is true about research design? a. Research design should be the first consideration in a research project. b. Research design decisions should be made after data analysis. c.

...Research Process Team C chose the Century National Bank data set for this research project. After reviewing the data for the bank, it seems some improvements are essential to its growth and viability. The research will begin by defining the purpose of the research and the problem that will be addressed. The team will review the research hypothesis, developed by the definition. These processes will start to develop the type of research and determine what is needed to retrieve useful information. Three principle types of questions to address in a research project are, relational, casual, or descriptive, depending on the reason for the research. Team C will use the descriptive type of study designed mainly to describe what is going on or what already exists. Questions to answer for researching the problems with Century National Bank should first identify the problem. The research could show how to determine the accessibility and availability of ATM’s to meet the customer needs. Researching the use of the banks services in contrast to other banks in the area could be helpful for the bank to determine the best value of its services to offer its customers. The research should show how many people are using the ATM with this bank’s ATM card versus other banks cards. In researching this statement spreadsheet for Century National Bank it shows many possible errors. The banks issue is not clear, concise or detailed....

Compare and Contrast Two Methods of Sociological Research.

...Research Methodology Aila Sajid Bhangoo Introduction A novice researcher often has a confusing start looking for answers to questions such as: what should be the focus of the research, what approach must be taken towards research that is how to go about data collection and how to draw the most accurate analysis from the information gathered. Consequently, it is of paramount significance what subject matter the researcher chooses, what research questions he conceives and how the researches goes about in conducting his research. There are primarily two aspirations for orchestrating a research; the first is to find a solution for an on ground problem present in the day to day political life which is called applied, practical or policy research and the second is with the aim of fostering and boosting the available knowledge about the politics and political world which is referred to as basic, pure or theoretical approach. Hakim defines policy research being concerned with ‘knowledge of action’; hence, it focuses on “actionable variables” or variables. The target audiences of such researches are policy makers in government, institutional decision makers, special interest groups and other relevant stakeholders....

...Research Process Paper Some individuals believe that education and earnings go hand in hand. The lesser the education, the smaller the wages, and thus with a greater education may lead to an increase in wages. The focus of this discussion will involve what the research process entails for the subject of wages and the relationship between education, and wage earnings. This research project will discuss the purpose of the research, define the problem, propose three possible hypothesizes, identify the variables, and define the problem in quantifiable measurements. According to some research studies the level of education that an individual obtains directly correlates to the wages that he or she will earn over his or her lifetime. The higher the degree of education that a person attains can affect the amount of wages that he or she will earn. Research shows that there is also a difference in wage earnings by males and females who have earned the same degrees. “The highest paid 10% of male workers with advanced degrees earned $3,260 or more weekly, compared to $2,252 or more for women of the same education level” (Wall Street Journal, 2009). The research suggests that there is an advantage of an increase in earning power by an individual who continues his or her education, and advances the degrees that he or she holds. This research may be important for anyone who is considering whether or not he or she should continue to further his or her education....

With the help of the research variables, the hypothesis is been prepared effectively from the variables. For preparing a good research variables there are different variables which match the research to make it effective in the process. There are attributes and values of the variables which can be changed accordingly. The flexibility is one of the qualities which a variable research consists and that is the most important consent while setting the research hypothesis. Two or more variables are needed to complete the research proposal. The variables have mutually exclusive attributes which occur at different time and are not selective for instance a person can select one alternative from the given options according to the study (Denise & Beck, 2004). This is helpful to prepare a research proposal as it may not take long time to conclude the research proposal. The variables are the factors which can be measured and they vary as per the name suggests. The variables improve the research proposal because they are the main base for the research which has to be taken for a particular business or a company....

Thesis Statement

...How To Write a Thesis Statement What is a Thesis Statement? Almost all of us—even if we don’t do it consciously—look early in an essay for a one- or two-sentence condensation of the argument or analysis that is to follow. We refer to that condensation as a thesis statement. Why Should Your Essay Contain a Thesis Statement? to test your ideas by distilling them into a sentence or two to better organize and develop your argument to provide your reader with a “guide” to your argument In general, your thesis statement will accomplish these goals if you think of the thesis as the answer to the question your paper explores. How Can You Write a Good Thesis Statement? Here are some helpful hints to get you started. You can either scroll down or select a link to a specific topic. How to Generate a Thesis Statement if the Topic is Assigned How to Generate a Thesis Statement if the Topic is not Assigned How to Tell a Strong Thesis Statement from a Weak One How to Generate a Thesis Statement if the Topic is Assigned Almost all assignments, no matter how complicated, can be reduced to a single question. Your first step, then, is to distill the assignment into a specific question.

...In quantitative research, researchers often test theories as an explanation for answers to their questions. In a quantitative dissertation, an entire section of a research proposal might be devoted to presenting the theory for the study. In qualitative research, the use of theory is much more varied. The inquirer may generate a theory as the final outcome of a study and place it at the end of a project, such as in grounded theory. In other qualitative studies, it comes at the beginning and provides a lens that shapes what is looked at and the questions asked, such as in ethnographies or in advocacy research. In mixed methods research, researchers may both test theories and generate them. Moreover, mixed methods research may contain a theoretical lens, such as a focus on feminist, racial, or class issues, that guides the entire study. I begin this chapter by focusing on theory use in a quantitative study. It reviews a definition of a theory, the use of variables in a quantitative study, the placement of theory in a quantitative study, and the alternative forms it might assume in a written plan. Procedures in identifying a theory are next presented, followed by a script of a theoretical perspective section of a quantitative research proposal. Then the discussion moves to the use of theory in a qualitative study....
