4.7 The importance of High response rate and the actual sample size required

The importance of a high response rate

The most important aspect of a probability sample is that it represents the population. A perfect representative sample is one that exactly represents the population from which it is taken. You, therefore, need to obtain as high a response rate as possible to ensure that your sample is representative. This requires you to determine the  minimum adjusted sample size , and finally the actual sample size required.

This note gives you a brief discussion on how to compute the adjusted sample size by considering the non responses , and also the  actual sample size you require for your research.
