Detailed explanation-1: -Quasi-experimental research is research that will include features of a true experiment, but some elements may be missing. Three types of quasi-experimental research are: cross-sectional, longitudinal, and cross-sequential. Cross-sectional research studies make a comparison of different groups at the same time.
Detailed explanation-2: -Cross-sectional research As it is a non-experimental design, it does not involve the manipulation of independent variables and does not assign participants randomly.
Detailed explanation-3: -Random assignment is an important part of control in experimental research, because it helps strengthen the internal validity of an experiment and avoid biases. In experiments, researchers manipulate an independent variable to assess its effect on a dependent variable, while controlling for other variables.
Detailed explanation-4: -The term true experiment is sometimes used to refer to any randomized experiment. In other instances, the term true experiment is used to describe all studies with at least one independent variable that is experimentally manipulated and with at least one dependent or outcome variable.
