To ensure the maximum benefit from the test in terms of accuracy, reliability and relevance.

Explanation:

Collecting the data is one of the most costly and time-consuming phases of any experiment or survey. Surveys in particular are easily misinterpreted, skewed or incomplete without proper and thorough pre-testing or pilot studies with small groups.

Before a large investment in time and materials is made to conduct any type of survey, several reviews should take place to ensure that the survey is unbiased, clear in it’s intent and unambiguous in the answers, contains internal checks and is of reasonable length.

It should be pre-tested with a reasonably representative sample of the target group to ensure that the questions are understood as intended. Only then can the expense of conducting and analyzing a survey be worth the value gained from the results.
