Students read tongue twisters in pairs and then we test who is better in the pair using parametric and non parametric t-test.
Goal
The goal is to see randomness in repeating the task even in one setting. To learn t-test in excel, R or python. Studnets also learn the limitatios of some tests - having test with 3 right answers will not give enough variation ot assess what you want to assess.
Structure
Students in pairs switch in reading tongue twisters and in measuring the time. Each tongue twister should be read at least three times, better to be read 5 times by each students. Number of mistakes is recorded as well as time.
