Professor Michaela Tran was interested in maximizing student learning in all her classes. She decided the best way to do that would be to investigate her students' test performance in a number of ways. The first thing she did was separate her students' test scores based on the time of day she held her lectures (morning vs evening). Next she recorded the type of test students were writing (multiple choice vs short answer). She selected a random sample of students from her morning (n = 7) and evening (n = 8) classes (total of 15) and recorded scores from two of their tests as shown below. 

Prof. Tran recently read an article that concluded students retained more information when attending classes in the morning. Based on this finding she thought students in her morning class might have performed better on their Short Answer test scores when compared to students in her evening class. Does the data support her hypothesis?Screen Shot 2018-08-07 at 7.31.34 PM.png
