AP PSYCHOLOGY

Detailed explanation-1: -Controlled experiments establish causality, whereas correlational studies only show associations between variables. In an experimental design, you manipulate an independent variable and measure its effect on a dependent variable. Other variables are controlled so they can’t impact the results.

Detailed explanation-2: -Experimental research allows the identification of causal relationships between entities or events. Successful experimental research depends on well-defined research hypotheses that specify the dependent variables to be observed and the independent variables to be controlled.

Detailed explanation-3: -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-4: -Experimental Research Researchers who want to test hypotheses about causal relationships between variables (i.e., their goal is to explain) need to use an experimental method. This is because the experimental method is the only method that allows us to determine causal relationships.

Detailed explanation-5: -Non-experimental research is research that lacks the manipulation of an independent variable. Rather than manipulating an independent variable, researchers conducting non-experimental research simply measure variables as they naturally occur (in the lab or real world).
