There are three basic types of experimental design. These include pre-experimental plans, actual experimental designs and quasi-experimental plans. The extent to which researchers assigned subjects to conditions and groups has differentiated the type of experimental design. This module will focus on different kinds of actual experimental design. The actual experimental design is characterized by a random selection of participants and a random assignment of participants to the group in the study. Researchers can also fully control external variables. Therefore, you can confidently determine that the influence on the dependent variable is directly attributable to the operation of the independent variable. For these reasons, true experimental design methods are often considered the best type of research planning method. There are several types of actual experimental design.

Quantitative research There are four main types of design: descriptive, relevant, quasi-experimental, experimental. The difference between the four types is mainly related to the degree that researchers designed to control experiment variables. The following is a brief description of each quantitative test design, and a comparison chart and comparative method. Quasi-experimental programming (often referred to as causal comparison) is aimed at establishing a causal relationship between two or more variables. Researchers do not assign groups and do not manipulate independent variables. Identify the control group and expose it to variables. Compare the result to the result of the group not exposed to the variable
