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?© BrainMass Inc. brainmass.com October 16, 2018, 10:38 pm ad1c9bdddf

Intrepeting Research - Independent Samples t-Test With SPSS
My assignment requires me to do a practice comparison of the means of two sample populations related to one particular variable. Using SPSS, I elected to do my population samples about gender: Female vs. males. The research was about which gender amongst the population researched make the highest income. I am having trouble reading/understanding/interpreting the results of the data. I have answered some of the questions but the following questions I am not sure of, can someone help me. The questions are below and a copy of the Output Results from SPSS is attached.
State the statistical assumptions for this test.
Using the data set you have selected, select independent and dependent variables.
Develop the null and the alternative hypothesis.
Use the SPSS to calculate an independent-samples t-test.
Report on the p-value and the confidence interval.
Interpret the confidence interval.
Decide whether to reject or retain the null hypothesis.
