When conducting scientific experiments, the researcher manipulates an "independent variable" (i.e., some physical parameter that can be controlled) in order to measure the effects of such manipulation on a "dependent variable" (i.e., the results of changing the physical parameter of interest). For example, one could lower the temperature in a refrigerator (the temperature being an independent variable) and wait to observe when water left in the refrigerator turns to ice (the change from liquid water to the solid form being the dependent variable). Thus, the change in the dependent variable depends on the manipulation of the independent variable.

The independent variable is the variable you change, the dependant variable is what changes as a result of what you change.

An independent variable is a factor that is intentionally manipulated in an experiment to observe its effect on the dependent variable. It is the variable that the researcher controls or changes to see how it influences the outcome of the study.

The independent variable is the variable being changed the dependent variable is the variable being measured.

If you were measuring the growth rate of plants under full sunlight for 8 hours a day versus plants that only have 4 hours of full sunlight per day, the amount of time per day of full sunlight would be the independent variable. This is what you control. The growth rate of the plants would be a dependent variable.
