Asking people to answer many questions about the concept of interest can increase the reliability of the survey or test. The more questions that are asked, the more reliable the results and the more complete the understanding of the construct of interest. However, the other options do not necessarily increase the reliability of the survey or test. Identifying a sample of individuals who are very similar to each other in terms of the construct of interest may improve the validity of the survey or test, but not necessarily the reliability. Asking people to respond to a few brief questions about the concept of interest may not be enough to accurately measure a construct and can lead to response bias.
