RESEARCH METHODOLOGY

Detailed explanation-1: -A control variable is an experimental condition or element that is kept the same throughout the experiment, and it is not of primary concern in the experiment, nor will it influence the outcome of the experiment.

Detailed explanation-2: -In experiments, researchers manipulate independent variables to test their effects on dependent variables. In a controlled experiment, all variables other than the independent variable are controlled or held constant so they don’t influence the dependent variable.

Detailed explanation-3: -Constant variables (also known as “constants") are simple to understand: they’re what stay the same during the experiment. Most experiments usually only have one independent variable and one dependent variable, but they will all have multiple constant variables.

Detailed explanation-4: -To control variables directly, all you need to do is hold them constant throughout a research or experiment (for instance, keeping the temperature constant). To control them indirectly, you can use methods like statistical control.

Detailed explanation-5: -Control variable-these are the elements that are kept the same during a scientific experiment. There can be multiple control variables. Any change to a controlled variable would invalidate the results, so it’s really important that they are kept the same throughout.
