Students were randomly assigned to two immersive learning treatments. Their performance on a year-end exam is measured (a continuous variable). What is the simplest test to see if there is a treatment effect?

Student's t-test

Explanation:

The student's t-test is used to compare, measure or evaluate two independent groups. It helps to show the significant differences between two groups that are significantly different from each other, in this case, the two immersive learning treatments.
