AP PSYCHOLOGY

Detailed explanation-1: -The independent variable is the variable that is manipulated by the experimenter. For example, in an experiment on the impact of sleep deprivation on test performance, sleep deprivation would be the independent variable.

Detailed explanation-2: -The independent variable (IV) in psychology is the characteristic of an experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.

Detailed explanation-3: -A manipulated variable, also known as an independent variable, is a part of an experiment that you can change to see how other variables respond. Here are the three types of variables in an experiment: Manipulated variable: The variable that you control and change based on the experiment.

Detailed explanation-4: -More specifically, in an experiment, a variable can cause something to change, be the result of something that changed, or be controlled so it has no effect on anything. Variables that cause something to change are called independent variables or manipulated variables.

Detailed explanation-5: -Independent variables are what researchers manipulate in a research study. An independent variable is the variable that researchers manipulate in order to better understand how phenomena, constructs, and behaviors are associated with dependent variables.
