In an experimental test with two randomly assigned groups, an experimental group and a control group, neither group is pretested before the treatment, and the treatment is then applied to the experimental group. Which kind of test is this?
APretest-only design
BPost-test-only design ✓ Correct
CPretest-post-test design
DOne-group pretest-post-test design
Correct answer: (B) Post-test-only design
Explanation
Two randomized groups with no pretest and treatment given only to the experimental group is a post-test-only design.
A pretest-only design is not a valid experimental form.
A pretest-post-test design measures both before and after treatment.
A one-group pretest-post-test design lacks a control group.
Randomization here substitutes for the missing pretest.
It compares the two groups solely on the final measure.
