2. Experimental and Measured variable: The experimental variables spell out the details of the investigators manipulations while the measured variables refer to measurements.

3. Active and Assigned variables: Any variablewhich can be manipulated is called active variable andif that cannot be manipulated is called assignedvariable.

4. Qualitative and Quantitative Variables: thequantitative variable is one whose values or categoriesconsist of numbers. On the other hand this variablecategory can be expressed numerically. But thequalitative variable consists of discrete categoriesrather than numerical units.

5. Moderator and Combined Variables: Themoderator variable is a secondary independent variablewhich is selected for study to determine if it affects therelationship between the primary independent variableand the dependent variable. On the other hand thecombined variable maintain the relationship with acause ,relationship and effects.
