Detailed explanation-1: -In an experiment, the independent variable is manipulated and the effects observed. These observed effects are called dependent variables. They are often the hypothesized outcome of manipulating the independent variable. A change in the dependent variable depends on the independent variable, hence the name.

Detailed explanation-2: -Dependent Variable The variable that depends on other factors that are measured. These variables are expected to change as a result of an experimental manipulation of the independent variable or variables. It is the presumed effect.

Detailed explanation-3: -Dependent Variable (aka Effect Variable) usually denoted as y, is a variable that is influenced to some extent by one or more other (independent) variables.

Detailed explanation-4: -The independent variable is the one the experimenter controls. The dependent variable is the variable that changes in response to the independent variable. The two variables may be related by cause and effect. If the independent variable changes, then the dependent variable is affected.

Detailed explanation-5: -A confounding variable, or confounder, affects the relationship between the independent and dependent variables.
