AP PSYCHOLOGY

Detailed explanation-1: -In experiments, researchers manipulate independent variables to test their effects on dependent variables. In a controlled experiment, all variables other than the independent variable are controlled or held constant so they don’t influence the dependent variable.

Detailed explanation-2: -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-3: -Answer and Explanation: The factor in an experiment that researchers manipulate so they can determine the effect is called the independent variable.

Detailed explanation-4: -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-5: -An experiment is a type of empirical study that features the manipulation of an independent variable, the measurement of a dependent variable, and control of extraneous variables.
