To test the effect of partial day care on academic performance in young children

Question

To test the effect of partial day care on academic performance in young children, you plan to use two groups of 4-year-olds from the same preschool class: one group is made up of randomly selected children who attend part-time day care; the other group includes randomly selected children who do not attend any day care other than preschool. Both groups will complete a brief test of academic performance during a regular preschool class. Which type of test should you use to compare the mean scores of the two groups?

Explanation / Answer

Independent samples t test.
