Overview
1. Watch this video on the t-test: Use it as a reference for your assignment.
2. Let's do a hypothetical experiment. Imagine that you are testing whether the number of emails each student in PY 354 send to their professor regarding their grades is related to whether the professor provides a grade calculator in the syllabus. In the first group, the control group, the professor does not provide a grade calculator. In group 2, the experimental group, the professor does provide a grade calculator in the syllabus. Complete an independent samples t-test using the following values for group 1 (control group): 5, 8, 10, 12, 12, 14, 15, 19, 20, 27 and group 2 (experimental group): 8, 7, 19, 19, 20, 26, 27, 28, 30, 30.
3. Provide your answers in an Excel sheet in your Discussion Board post. Explain whether there is a statistically significant difference between these two groups (p < .05). Then, explain what this means regarding the experimental manipulation.
