The first illustration involves a re-analysis of data from a study. This section describes different types of evaluation designs and outlines advantages and disadvantages of each. Many alternative designs can also be created by adding a comparison group, follow-up test, retrospective pretest, and/or intermediate testing to the designs identified below. Posttest only Data are collected at the end of the program. A pretest posttest design is an experiment where measurements are taken both before and after a treatment.

Experimental research design 1. INTRODUCTION Research design is the framework or guide used for the planning, implementation, and analysis of a study. It is a systematic plan of what is to be done, how it will be done, and how the data will be analysed. Experimentation is the most scientifically sophisticated research. Pre-Experimental Designs. Pre-experiments are the simplest form of research design. In a pre-experiment either a single group or multiple groups are observed subsequent to some agent or treatment presumed to cause change. Types of Pre-Experimental Design. One-shot case study design; One-group pretest-posttest design; Static-group comparison. What are the advantages and disadvantages of posttest only design and pretest-posttest design? Advantage of posttest only design is it will eliminate a potential for confounding variable and allows for comparison of two groups. Disadvantage of posttest only design is that the experiment almost needs to be flawless and well thought out to ensure. Pretest-posttest designs and measurement of. change. that pretest-posttest designs in experimental research, are suitable to be used to compare groups and measure changes in pretest and posttest data. and social motives while male master level runners were statistically significant only in the subcategory of competition.
Quantitative Research Designs Experiments, Quasi-Experiments, & Factorial Designs Experimental research in communication is conducted in order to establish causal relationships between variables. Alternate explanations can be eliminated only when high control is exercised. Control, therefore, is the key characteristic of an experiment.
