A Quasi – Experimental Design versus Experiment Design

Introduction
A researcher must, first of all, understand the topic of interest for the study and then evaluate the type of research approach that applies to use. A research design is a model that allows the researcher to find solutions to anticipated problems and criterion for the various stages of the study (Frankfort-Nachmias & Nachmias, 2008). Frankfort-Nachmias &andNachmias (2008), discussed that there is three distinguished quantitative research designed, and they are experimental, quasi-experimental and correlational/ pre-experimental designs. I this paper the author will discuss assess the strength and limitation of the According to Frankfort-Nachmias and Nachmias (2008) the experimental design allows for pretest, posttest and control/experimental group comparisons; it allows the researcher r to control the independent variable and then grit the arrangement by adding randomized groups that control the external and internal validity.
Experiment and Quasi –Experimental Design
According to Frankfort-Nachmias and Nachmias (2008) the experimental design allows for pretest, posttest and control/experimental group comparisons; it allows the researcher r to control the independent variable and then grit the arrangement by adding randomized groups that control the external and internal validity. Experimental research investigates to conclude if a particular treatment impact an outcome (Creswell, 2009) Experiment deign include true experiments with the random assignment of the subjects to treatment conditions and quasi- experiments is the one that used nonrandomized design (Creswell, 2009). Quasi –experiment is when the participants are not randomly assigned(Creswell, 2009).
Strength of Experiment design
Creswell explains that true experiment eradicates any chances of the systemic variety of the participants that could affect the outcome (Creswell, 2009). According to Frankfort-Nachmias and...
