Question

Suppose you collect data on GPAs by classroom row in which the student chose to sit, and that there are four rows. Suppose you do multiple two-sample t-tests to compare the mean GPA of the rows, and discover that the p-value comparing the means of Row 1 and Row 4 is 0.025. Would it be correct to say that the difference in mean GPA is statistically significant for Row 1 and Row 4? Explain.
