One quantitative research method is the pre- and posttest research model. This method requires testing whether the independent variable (factor) influenced the results of measuring the dependent variable. The use of pre- and post-test measures requires that a certain variable be measured at least twice.
Pre-test and post-test are two types of surveys that can be used to evaluate the effectiveness of various activities, such as advertising, education or marketing. A pre-test involves conducting a survey prior to the introduction of a particular advertising campaign, educational program or other activity to determine the level of knowledge, attitudes and behavior of consumers prior to the activity. The results of the pre-test provide a baseline for the post-test to assess what changes have occurred after the introduction of the activity. The post-test involves conducting a survey after the introduction of a given advertising campaign, educational program or other activity to determine what changes have occurred in the level of knowledge, attitudes and behavior of consumers after the activities began. The results of the post-test are compared with the results of the pre-test to assess the effectiveness of the activities. Pre-test and post-test can be used in various fields such as advertising, education, marketing, product testing, service testing, etc. They can be used to evaluate the effectiveness of advertising campaigns, educational programs, new products or services, and to assess the effectiveness of CSR activities.
