Question

A teacher wants to know if alcohol improves test performance. He separates 24 students into three groups by random assignment. Group 1 is sent to a study group for 3 hours before the test. Group 2 is sent to the gym for three hours before the test, and Group 3 is sent to a bar for three hours before the test. After the three hours, the students are tested. What would be the best statistical test to show if alcohol had any affect between the three groups?

Answer 1

Answer:

ANOVA

Explanation:

According to my research on different statistical tests, I can say that based on the information provided within the question the best test would be ANOVA. Analysis of variance (ANOVA) is a collection of statistical models and their associated estimation procedures used to analyze the differences among group means in a set of data. Which is the best method when analyzing three groups, while for 2 groups the best method would be an independent t-test.
