Independent sample t test in SPSS

EXERCISE #1: DATA LOADING & DESCRIPTIVE STATISTICS.

Imagine that stimulus students are asked to indicate how likely they are to use a new breakfast-food/ toothpaste combination. The rating scale ranges from 0 (no chance of using the product) to 100 (certain to use the product). Your trustworthy but confused lab assistant hands you these ratings from eighteen men and eighteen women who tried Cheerio-Paste:

Student: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
Male: 25 38 50 55 22 30 35 50 63 45 65 68 80 75 55 70 45 82

Female: 35 40 55 65 68 75 80 65 68 35 55 20 35 25 50 45 40 28

Create an SPSS data file for these data.

ANSWER THE FOLLOWING AND SUBMIT

1. Entering the dependent variable is the easy part....start there. How many dependent variables are there?

2. What is the readily apparent independent variable? How do you identify it in the file?

3. Oh yes...the ratings in bold print are all from transfer students. The ratings in normal print are from traditional 4-year Hamline students. What kind of variable distinguishes traditional students from transfer students? Once again, how do you identify it in the file?

4. What kind of metric (scale) are the ratings?
