PROPOSAL GUIDELINES

QUANTITATIVE PROJECT


 

 

The proposal should be a maximum of two double spaced pages covering the following points:

 

 

RESEARCH OBJECTIVE

 

What do you hope to accomplish with this research?  What is your research question?

 

 

HYPOTHESES AND EXPECTATIONS

 

What do you expect?  What are your independent and dependent variables?  Draw diagrams of how you expect your independent and dependent variables to be related in your test of hypotheses. Your hypotheses and expectations will give you guidelines for what data you want to collect.

 

 

METHODOLOGY

 

How are you going to conduct your research? You need to talk about:

 

Technique – You will be doing survey research. Attach a draft of your questionnaire so we can discuss it. The questionnaire should be at least two pages long.  The questionnaire should also contain a scale. You can make up the scale or get a scale from previous studies.  The questionnaire should also contain some demographic information such as sex and/or class of student. You need to pay attention to transitional statements, skip patterns, question wording, question grouping, and question order. Here is a cover letter to go with the questionnaire.

 

Sampling – how are you going to choose subjects? I think that about 30 respondents is a large enough sample for this project.

 

Pretest – You will need to pretest your questionnaire on at least 3 people. Make notes on what is said and how it led you to change your questionnaire.  For example, did the respondents understand your scale?  You do not have to pretest before meeting with me, but it is a good idea.

 

Data Coding – what are your plans for coding or describing the data?  You will need to create a codebook.

 

Analysis – how do you plan to analyze the data? You should do a regression analysis, so you will need at least two interval level variables, one for your independent variable and one for your dependent variable. One dependent variable could be the scale you create. Remember that age is not a good continuous or interval level variable for studying undergraduates because there is so little variation in the variable. (Just about everyone is between 17-23.) You can also do cross tabulation, descriptive statistics, scatterplots, etc.  What is your plan?

To be more specific in terms of statistics, you should think about looking at descriptive statistics such as the mean, and descriptive displays such as barcharts for variables with a few categories, histograms and boxplots for variables with continuous distributions, and scatterplots for the relationships between two continuous variables. You also need to think about testing the relationships between variables such as the t-test for the relationship of a categorical variable with two categories such as gender and a continuous variable. A table or crosstabulation of data can be used to display two categorical variables, and the relationship can be tested with the chi-square test. The relationship between two continuous variables can be tested with a regression analysis. All of these techniques will be covered in class.

In terms of data collection this means that you will need to collect categorical data such as gender and class of the respondent, and a scale and other continuous variables.

Creating a Scale:

You will need to create a scale as part of this project. A scale is composed of a number of statements about something that you want to study. You should have at least four items in your scale, but more is better. The items should be expressed as declarative statements that the respondent can have an opinion about. For example, if you wanted to study whether students were polite, you could create a scale of politeness based on the students opinions about whether they engage in rude behavior that could look something like this:

1. You should send a written thank you note if you receive a present.

2. You should rarely honk your horn while driving a car.

3. You should say "bless you" if someone sneezes.

4. You should hold doors open for others who are behind you.

For this scale you could create response categories such as "strongly agree", "agree", "neutral", "disagree", or "strongly disagree". Then you could code the responses from 1 to 5, add up the responses for a respondent, and get a attitude towards politeness scale value. Then you might want to test hypotheses such as males score higher on politeness than females. Your independent variable would be gender and your dependent variable would be the politeness scale. You might also have a continuous or interval level scale variable that would predict politeness, such as the number of hours of sleep you get a night. In this case you would predict that number of hours of sleep would predict your politeness score.

There are several points to keep in mind when creating a scale. First, you have to come up with statements that the respondent can agree or disagree with. If you asked "How polite are you?" or "Do you think you are a polite person?" then people will want to answer yes or no and a 5 point agreement scale would not make much sense. This is why you need to express your scale questions as declarative statements such as "The world is reaching the limits of people it can hold", so that people can have levels of agreement or disagreement. Another point to keep in mind is that all of your statements have to address the same underlying topic. If you added a statement to your politeness scale such as "I always yell at football games", you may not be measuring politeness, but rather excitement at sports contests. It is a good strategy to think of more statements than you are going to use in your final scale and then give the scale to some people. See if they consistently agree or disagree with the items, and, if they are not consistent in their answers, ask them why they scored some items as agree and some as disagree. You may find that they did not interpret all of the items as measuring what you thought the items would measure. In this case, you can delete some items and develop a more accurate scale. Finally, don't hesitate to look on the internet or the research literature for scales. You should feel free to use published scales in your project. You can search our library's databases of psycINFO or psycARTICLES of academic psychology articles using psychological scales. Occasionally the article will list the items used in a scale in an appendix. You can also go to the Research Methods Division of the Academy of Management and click on "Measure Chest" to find a database of scales and references of where to find them.

 

Example:  A previous group studied cell phone use among the undergraduates.  Some of their initial hypotheses were that women would use cell phones more than men and type of phone plan would affect usage. They could have compared number of minutes used per week by men and women by by looking at two boxplots. This would tell them the difference between men and women (categorical or nominal variable) on number of minutes used (continuous or interval variable). The difference could be tested with a t-test. They could have created a scale with a number of questions about how convenient the respondent found cell phones.  By adding up the responses to these attitude questions, the group would create a continuous or interval variable measuring satisfaction with the cell phone. 

 

They could have proposed a causal hypothesis: higher satisfaction with their cell phone leads to more cell phone minutes.

 

 

 

 

 


Then they could have done a regression test using satisfaction (independent variable) to predict minutes of cell phone use (dependent variable).

 
Other examples of student projects:

Research Question: Are you satisfied with the Plex?

Hypotheses: Gender would affect your attitude towards the Plex. The type of usage of the Plex would affect your attitude towards the Plex. Frequency of use would affect your attitude towards the Plex. The students came up with an attitude towards the Plex scale based on the respondent's opinions of different features of the Plex.

Research Question: Yankees Fans vs. Red Sox Fans: Who is Smarter?

Hypotheses: Red Sox fans are more enthusiastic about their team than Yankees fans. Yankees fans are more academically dedicated than Red Sox fans. The more enthusiastic fans are about their baseball teams, the less academically dedicated they will be.

For this study the students had to generate scales for baseball team enthusiasm and academic dedication. For example, academic dedication was measured by "How many books did you read during the summer of 2xxx?", On average, how many hours each week do you study for tests?", "On average, how many times each month do you skip class?". Note that in this case, the students are created a scale based on how many times certain behaviors take place. They had the respondents checking off categories such as "0", "1-2", 3-4". Then they coded the categories as 1, 2, 3, etc. and added them up to get a score. I am not sure that the number of books read during the summer measures "academic dedication", and I would have suggested dropping this question and focusing on academic school year efforts. These questions could also be focused by asking "Last month, how many times did you skip class?" rather than "On average ...". Recall of behaviors is likely to be more accurate if the respondent is thinking of more recent behavior.
