A quasi-experimental design is the second kind of research that looks a little like an experimental design but the subjects are not randomly assigned to the groups [6]. Altogen Labs provides service of stable cell line development completed in 28 days. Experimental designs have been developed to reduce biases of all kinds as much as possible. ESSENTIAL CHARACTERISTICS A true experimental design consists of three important characteristics. We will review the major sources of bias in the section on threats to internal and external validity. For example: Letâs see if the drug amphetamine (a stimulant) affects learning.
