The Timing of Measurement E

The timing of measurement e.g., pretest, posttest, after treatment) is an important consideration in experimental design because:

A) Various times may produce larger effects than others
B) Various times may produce smaller effects than others
C) Measures given before the experimental manipulation or treatment i.e., pretest) may be the best estimate of the participant
D) Results may be determined by the timing of the measurement in that different times may produce different results
