You determine the average response time (RT) of two groups of students on a test where sentences and pictures must be matched. One group consists of 10 students who have Dutch as their mother tongue, the other group consists of 10 students with other mother tongues. You perform an appropriate test to check if the groups differ in RT. After performing the test, the p-value turns out to be 0.02 (two sided). What does this mean?
Antwoord: If the groups are equal, the chance of samples with this or a bigger difference is 2%.
