EVERYDAY SCIENCE

Detailed explanation-1: -A dependent variable is what changes as a result of the independent variable manipulation in experiments. It’s what you’re interested in measuring, and it “depends” on your independent variable. In statistics, dependent variables are also called: Response variables (they respond to a change in another variable)

Detailed explanation-2: -There must be at least two variables in any experiment: a manipulated variable and a responding variable. A control is a variable that must be held constant so it won’t influence the outcome of an experiment.

Detailed explanation-3: -Sometimes, in order to control the intervening variables the researcher may have to identify and measure them. Apart from the measurement of intervening variables, the dependent variable (variable under investigation) has also to be measured so as to see what changes have been brought about by the treatment.

Detailed explanation-4: -When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer? Independent.
