The company was advised to carry out pretests on all electrical goods.
1 to do a test on a product, piece of equipment, etc. to make sure it works before it is sold or used: --
To this end, a pretest-posttest experimental design with a control group was adopted.
These were asked at pretest and in the mailed posttest.
The between-subjects variable is group (treatment or control), and the within-subjects variable is time (pretest and immediate posttest).
In order to be admitted to the study, participants' scores on the controlled production pretest had to be 0 out of 10 points.
Ideally we would have liked to have pretest-posttest differences to show, but due to time and finance constraints this was not possible.
The issues examined are those relevant to large-scale population screening of women considered at low pretest risk of carrying an affected fetus.
In each pretest, subjects were presented with highly familiar, monosyllabic words (not the experimental words) in lists varying from 3 to 4 words.
Three demonstration trials and three practice trials preceded eight pretest trials.
