BACHELOR OF BUSINESS ADMINISTRATION

Detailed explanation-1: -A pretest is an assessment measure given to participants before they have undergone some type of treatment as part of a research study, while a posttest is an assessment measure given to participants after they have received treatment as part of a research study.

Detailed explanation-2: -An advantage of a pre-test and post-test study design is that there is a directionality of the research, meaning there is testing of a dependent variable (knowledge or attitude) before and after intervention with an independent variable (training or an information presentation session).

Detailed explanation-3: -Example: All students in a certain class take a pre-test. The teacher then uses a certain teaching technique for one week and administers a post-test of similar difficulty. She then analyzes the differences between the pre-test and post-test scores to see if the teaching technique had a significant effect on scores.

Detailed explanation-4: -In a pretest-postest design, a sample is randomly assigned to two or more groups (usually one or more treatment groups and one control group); Subjects in each group are measured at two time periods: pretest (before treatment) and posttest (after treatment). Subjects in the same group receive the same treatment.
