Lecture 8 – Hypothesis Testing Process of Hypothesis Testing The procedure of hypothesis testing is the same for different RQs. What is different is 1. The test you use, and 2. How to interpret the results if you reject the null hypothesis One sample t-test - Compare the average value of one variable to a constant - Variable needs to be metric o E.g. is the mean service rating above 5? o Is average customer spending equal to \$500? Paired samples t-test - Compare the average value of two variables - Both variables need to be metric o E.g. is consumers mean willingness to pay for iPhone 7 different from that of Samsung 7? o Do student’s average preference for solving math problems differ from that of working on creative tasks? Two independent samples t test - Compare the average value of one variable from two different groups - Variable of comparison – metric - Grouping variable – categorical o E.g. does the mean rating for new iPhone 7 differ between users and non- users? o Do men and women differ in average satisfaction with crown casino?
