Detailed explanation-1: -A variable is a quantity whose value can change. A constant is an unchanging quantity. In any experiment, the value of one quantity must be systematically changed in order to measure its effect on another quantity. The quantity that the experimenter chooses to change is called the independent variable.
Detailed explanation-2: -An independent variable is the variable you manipulate, control, or vary in an experimental study to explore its effects. It’s called “independent” because it’s not influenced by any other variables in the study.
Detailed explanation-3: -Answer and Explanation: The independent variable is a variable that the researcher can control and whose change results in the change of the dependent variable. The dependent variable changes, because of a change in the independent variable is the underlying assumption of a simple linear in regression.
Detailed explanation-4: -Answer and Explanation: FALSE . The dependent variable doesn’t affect the independent variable.
