Question
A researcher wanted to know if there is a relationship between gender and academic performance in high school students. For a sample of n = 100 students the researcher recorded a student’s final letter grade (i.e., A, B, C, D and F grades) and number of females and males in each letter grade category. What statistical test should the researcher use to test if there is a relationship between gender and the final letter grades received by high school students?
A. 1- factor Anova B. Pearson’s correlation C. Chi2 for Independence D. t- test for repeated-measuresExplanation / Answer
Here as we are trying to find the relationship between 2 categorical variables, this would be done by a chi square test for independence.
The chi-square (2) test of independence is used to test for a statistically significant relationship between two categorical variables. This is an inferential test that uses data from a sample to make conclusions about the relationship between categorical variables in the population.
Therefore Chi2 test for independence is the correct answer here.
