AP PSYCHOLOGY

Detailed explanation-1: -In a psychology experiment, researchers study how changes in one variable (the independent variable) change another variable (the dependent variable). 2 Manipulating independent variables and measuring the effect on dependent variables allows researchers to draw conclusions about cause-and-effect relationships.

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

Detailed explanation-3: -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-4: -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.

Detailed explanation-5: -Answer and Explanation: The correct answer is a. It is the variable that the experimenter manipulates. The effect is the dependent variable, which is influenced as a direct result of the independent variable, which, in turn, is under the control of the researcher.
