Which of the following threats to internal validity is present in a one

Another threat to the internal validity of one-group pretest-posttest designs is testing , which refers to when the act of measuring the dependent variable during the pretest affects participants' responses at posttest.

What is the main problem of a one

The one-group pretest–posttest research design does not account for many confounding variables that may threaten the internal validity of a study.
