Arizona State University SPSS Project

Make sure to complete the SPSS lab assignment for this week first, then work on the homework. The homework applies the skills you learned in the lab with a different dataset. Especially as you are working on these specific hypothesis tests, it will be increasingly important to refer to the lab for this module for guidance on how to approach the homework assignment.

Choose a variable from this dataset that meet the requirements for the one-sample t-test. 

Write out the null and alternative hypotheses appropriate for this test. 

**NOTE: part of a one-sample t-test is comparing the group mean to a theoretical threshold. For example, if you have scores from 0-100, you might compare the mean to 75. Because you might choose different variables to conduct this test, choose a theoretical comparison number to compare the group mean to that works for your chosen variable, just make sure to be explicit about what that number is in your write up.

Test the assumptions for the one-sample t-test and demonstrate whether the data meet the assumptions. 

• Conduct the test and interpret the results. What did you find?
