What is an index and how does it improve the ability of a survey to obtain information about a specific topic?
What will be an ideal response?
Ans: Varies.
An index is the average or sum of a set of questions all aimed to measure the same concept. Clear questions are often difficult to write and people may interpret them in idiosyncratic ways. To help prevent that form of error from having too much of an influence on the data, researchers can incorporate numerous questions aimed at the same topic and “average out” the idiosyncrasies involved in the interpretation of any one question. The result is a more complete measure of a concept than any one particular question can provide.
