Question

A student is considering doing a complete repeated measures design experiment involving motor skills. The student's advisor has told him that people show a large initial improvement on the task followed by slow steady improvement after this initial change. The student must choose a technique for balancing practice effects. Which technique should the student NOT use?
a. block randomization
b. latin square
c. ABBA counterbalancing
d. all possible orders

Answer 1

Answer:

c. ABBA counterbalancing

Explanation:

The student should not use the method because it is a progressive error management technique for each subject by introducing all treatment circumstances twice, first in one sequence, then in the other (AB, BA) by subject counterbalancing.

If participants experience conditions more than once, they experience the conditions first in one order, then the opposite order.
