A is the answer of the federal government
Answer:
The answer is construct validity.
Explanation:
Construct validity is described as the degree in which a study<em> actually</em> measures what it claims to be measuring. A well-designed research will ideally have high construct validy, while a poorly designed one may confound the variables and result in measuring a different aspect.
For example, if a researcher tries to find which of two perfumes is more attractive to customers, <u>but uses different shaped or coloured bottles</u>, it's possible that the test will lack construct validity (the bottles may affect the customers' opinions).

This term is defined as the costs that change as the quantity of the product that is being produced changes.
