After submitting her last exam, Godzilla feels nostalgic for all the statistical shenanigans you put her through. She decides to make her life complicated one more time in 2021 and runs an experiment. She knows that to study for exams, students either used study groups or studied individually. She also knows that half of the students in her class had to work part time while studying for their exams. She takes a total of 32 students (8 in each group) and measures whether there was an interaction effect for studying method and working part time. She takes the final test grades from each student in the class (out of 100)

Part time?
Yes	No
Study type	Group	82	96
	84	92
	88	96
	84	98
	80	96
	78	94
	82	94
	84	98
	Individual	75	86
	74	82
	70	86
	76	88

2. Based on Levene’s Test of Variances, can we trust our data? Yes or No

3. Which group combination had the lowest test scores? ____________________

4. In your own words (use textbook as template), describe the interaction effect observed in this data.

E.C) Reading the following experimental set up, tell me what type of Factorial ANOVA design this is (ie 2x2, 2x2x2, 2x2x2x2 etc)
