RESEARCH METHODOLOGY

Detailed explanation-1: -A dependent variable is the variable that changes as a result of the independent variable manipulation. It’s the outcome 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: -Now common understanding from science tells you that several factors are affecting the growth of tomatoes: sunlight, water, kind of soil, and nutrients in soil. How fast the tomato seedlings will grow and bear fruits will depend on these factors.

Detailed explanation-3: -In this experiment, the addition of fertilizer is the independent variable manipulated by the scientist. Plant height is the dependent variable that responds to the change in the independent variable. Each plant is exposed to an equal amount of sunlight, so sunlight is the control variable.

Detailed explanation-4: -The tomato hypothesis: soda will grow the tallest tomato plants. This educated guess is about the relationship between the independent and dependent variables. The independent variable (the liquid) is intentionally manipulated or changed during the experiment.
