design model best fits this study?
Answer:
A quasi-experimental design (QED) according to Trochim (2006), "is one
that looks a bit like an experimental design but lacks the key ingredient --
andom assignment." So, to make this much clearer, it is important to define
an experimental research design (ERD). According to Research Connections
(2013) an, "experiment is a study in which the researcher manipulates the
level of some independent variable and then measures the outcome.
Experiments are powerful techniques for evaluating cause-and-effect
elationships. Many researchers consider experiments the gold standard
against which all other research designs should be judged. Experiments are
conducted both in the laboratory and in real life situations." ERD is a 'true
experiment' wherein all important factors and variables are completely
controlled and participants or subjects are...
