Detailed explanation-1: -Experimental design is the process of carrying out research in an objective and controlled fashion so that precision is maximized and specific conclusions can be drawn regarding a hypothesis statement. Generally, the purpose is to establish the effect that a factor or independent variable has on a dependent variable.
Detailed explanation-2: -Question 4 What is an experimental design tool that can be used to address variables that may be confounders at the design phase of an experiment? Using regression models.
Detailed explanation-3: -There are several methods you can use to decrease the impact of confounding variables on your research: restriction, matching, statistical control and randomization. In restriction, you restrict your sample by only including certain subjects that have the same values of potential confounding variables.
Detailed explanation-4: -Random assignment is the most important technique used to control for confounding variables because it has the ability to control for both known and unknown confounding extraneous variables. Because of this characteristic, you should randomly assign whenever and wherever possible.
