Question

What are the three methods of evaluating the validity of dependent variables?

1) Experimental method, Observational method, and Correlational method
2) Qualitative method, Quantitative method, and Experimental method
3) Controlled method, Uncontrolled method, and Descriptive method
4) Independent method, Dependent method, and Control method

Answer 1

The three methods of evaluating dependent variables are the Experimental method, Observational method, and Correlational method.

Step-by-step explanation:

The three methods of evaluating the validity of dependent variables are the Experimental method, Observational method, and Correlational method.

The Experimental method involves manipulating an independent variable to observe its effect on a dependent variable.

The Observational method involves carefully observing and recording data without manipulating any variables.

The Correlational method examines the relationship between two or more variables without establishing cause and effect.
