QUESTION 4

To analyze whether there is a significant difference between IQ, GPA, and math anxiety level (MathAnx) based on class, where class is coded as (1 = freshmen, 2 = sophomores, 3 = juniors, 4 = seniors), you can use analysis of variance (ANOVA). ANOVA is appropriate when you want to compare means across more than two groups.

Hypotheses:

Null Hypothesis (H0): There is no significant difference in IQ, GPA, and MathAnx levels across different classes.
Alternative Hypothesis (Ha): There is a significant difference in IQ, GPA, and MathAnx levels across different classes.
