The current study investigated the EIV method and compared it to change scores and analysis of covariance (ANCOVA) in a two group pretest-posttest design. Results indicated that the EIV method's estimates were unbiased under many conditions, but the EIV method consistently demonstrated lower ...
The simplest of all experimental designs is the two-group posttest-only randomized experiment. In design notation, it has two lines – one for each group – with an R at the beginning of each line to indicate that the groups were randomly assigned. One group gets the treatment or program ...
What is the impact of using thentest ratings instead of true pretest ratings on performance gain as calculated with the novel evaluation tool? (2) How does the design of the data collection tool (i.e. sequential data collection vs. direct comparison of thentest and posttest ratings for spe...
This study examines the relative effectiveness of two means of analyzing the pre-test/post-test control group experimental design. Samples were randomly drawn from a standardized normal population and assigned to one of the four cells of the design. A set of experimental differences were induced in...

To investigate such effect(s), this study adopted a pretest-posttest design involving 147 intermediate-level learners of English as a second language. Using the Group Embedded Figures Test, participants were divided into two groups: field dependent and field independent learners. For 4 weeks, both...
A four-person committee is to be formed from an group of eight chemists. How many unique committee can be formed? In how many ways can you make groups of 3 out of 11 people? What are the limitations of a nonequivalent control group p...
In 2021, 168 students participated, and a quantitative questionnaire using a pretest-posttest design was applied to assess the curriculum’s impact on students’ knowledge and attitudes toward end of life care. In 2022, 157 students participated, and the survey used open-ended questionnaires (the...
