I want to know if my study program is more effective than my competitors study program in increasing college students’ GPAs. I use a convenience sample and compare students using my program to students in my competitor’s program. Average GPA at graduation with my program 3.3, 3.6, 3.9, 4.0, 3.1 Average GPA with competitor’s program 3.9, 3.3, 3.6, 2.8, 3.3 What is the correct statistical test for this experiment?
Here we use 2 sample t test.
Hence there is insufficient evidence to conclude that my study program is more effective than my competitors study program in increasing college students’ GPAs.
