RESEARCH METHODOLOGY

Detailed explanation-1: -A controlled experiment is defined as an experiment in which all the variable factors in an experimental group and a comparison control group are kept the same except for one variable factor in the experimental group that is changed or altered.

Detailed explanation-2: -An experiment in which only one variable is manipulated at a time is called a controlled experiment.

Detailed explanation-3: -A controlled experiment is simply an experiment in which all factors are held constant except for one: the independent variable.

Detailed explanation-4: -In a controlled experiment, all extraneous variables are held constant so that they can’t influence the results. Controlled experiments require: A control group that receives a standard treatment, a fake treatment, or no treatment. Random assignment of participants to ensure the groups are equivalent.

Detailed explanation-5: -Independent variables (IV): These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable.
