Answer 1

Validity of a research can be improved by d) Both the above measures

A true sample vs an imaginary sample

• A true sample will help a researcher gain more authentic results which he could validate.
• On the other hands, imaginary samples do not provide authentic results and might be discarded.

Eliminating  extraneous factors vs not eliminating extraneous factors

• If extraneous factors are present in a research, the results will be influenced by these factors and will not be authentic.
• On the other hand, eliminating extraneous factors provides authentic results.
