In this study, we want to examine the effects of both the type of communication platform and the ideal group size, and to understand the interactions between platform and group size on the dependent variables (participant outcomes). One common type of experiment is known as a 2×2 factorial design One of the most commonly used experimental designs in the field of clinical research is the 2×2 factorial design

This type of design is beneficial in examining the effect of two different intervention factors and their interaction on an outcome variable.
What is a 2×2 factorial design
A 2×2 factorial design is a type of experiment that involves multiple independent variables and multiple levels, or conditions, of each variable It is an important tool in research because it allows the researcher to study the effects of two or more variables on a single outcome at the same time. Such a design allows the comparison of the levels of factor a (a main effects), the comparison of the levels of factor b (b main effects), and the investigation of a × b interactions There are some issues to consider prior to conducting of a factorial clinical trial.
The definition of factorial design is an experiment that has multiple factors or independent variables It requires a minimum of two independent variables, whereas a basic experiment only. My study is a 2x2 design Iv2 = control / experimental groups
Physicians, illustrates some features and potential problems in the design and analysis of a factorial trial.
