Detailed explanation-1: -In experimental studies, but NOT in other studies, the researcher manipulates the independent variables. one assigned variable and one active variable. experimental control.
Detailed explanation-2: -An independent variable is the variable that researchers manipulate in order to better understand how phenomena, constructs, and behaviors are associated with dependent variables. Within applied statistics and research, the independent variable is often a “grouping” variable that is categorical in nature.
Detailed explanation-3: -Nonexperimental research is research that lacks the manipulation of an independent variable, control of extraneous variables through random assignment, or both. There are three broad types of nonexperimental research. Single-variable research focuses on a single variable rather than a relationship between variables.
