Assignment #5

For all computer assignments:

You are expected to do your own work. You may seek help from others to learn how to carry out a procedure, but you are to do all aspects of the assignment yourself Therefore you should work through the complete assignment seeking help as necessary. If you do so without help - great. However if you have had help along the way with any aspect of a major component of the assignment (the major components are underlined on the assignment handouts), then you should repeat the work on that component from beginning to end on your own. The work you turn in should represent your independent working of the assignment. Also, your typed responses to the interpretation items should be phrased in your own words. The cover sheets that you sign will attest to this.

For this assignment:

- Define the variables:

- use the column heads for variable names

- each variable is numeric; make the width appropriate to the values for the variable (all are whole numbers and should have decimal= 0 )

label each variable (subject = subject number; group= type of course; score = score on research project)

value labels are necessary for group (1=integrated course; 2= traditional course)

make column width equal to 8

select the appropriate scale for each variable

- Enter data- print a case summary for all variables and check data entry

- Analyze data:

Use EXPLORE (Analyze>Descriptive Statistics>Explore) to get descriptives for score separately for each group (integrated and traditional). Note: Dependent = score, Factor = group, be sure that you select "both" under Display. Also, click the "statistics" button and make sure Descriptives is checked; then click "continue". Next, click the "plots" button and make sure that "Factor levels together" is selected under boxplots and that "stem-and- leaf' is deselected). Now click "Continue" and "OK".

Do an independent samples T-TEST (Analyze>Compare Means>Independent- samples T-test) on score to determine if the two groups are significantly different. Note: Test variable is score and the Grouping variable is group. Define groups (group1=1; group2 =2). Click "Continue" and "OK".

- Do an Error Bar Graph for the group means (Graphs>Error Bar). Select Simple and Summaries for Groups of Cases. Define: (Variable = score and category axis= group). "OK".

- Answer the following in writing:

1. Write a discussion of the appropriateness of the independent - samples t-test in this situation- think: (1) hypothesis and (2) assumptions of independent random samples, normality, and score-level data
2. On the basis of Levine's test, which row oft-test results should be used?
3. What is the appropriate value of t? What is the one tailed p-value associated with this t?
4. Write an interpretation of the results of the t-test and the implications for the study.
