statistics and statistical inference. An important set of techniques is that related to statistical surveys. In any instance, an appropriate type of statistical analysis should take account of the various types of error that may arise, as outlined below.

The following section is a step-by-step guide to conducting an interview. You should remember that all situations are different and therefore you may need refinements to the approach.

Concerns that cut across all designs: criteria for accessing quality
