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).
Technology development over the years
Asking someone to check your speech in advance to ensure its accuracy will help you avoid making blunders.
The degree to which an expression or measurement conforms to a genuine value is known as accuracy. Additionally, it concerns accuracy or the lack thereof. In other domains, such as science, the term is more precisely defined; it is distinguished from precision.
Accuracy refers to how closely the measurement resembles the actual value. It's important to achieve the same result every time you take a measurement in order to be reliable.
Consider how shooting at a target would be like taking measurements. The target, or bullseye, stands in for the real worth you're attempting to gauge.
Doctors and researchers use the phrases accuracy sensitivity and specificity when discussing the accuracy of medical testing. These metrics let us know how accurately a test can determine whether or not a person has a condition.
