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.

4.6 What sample size do I need for my research?


 What sample size do I need for my research?
 Perhaps the most frequently asked question concerning the determination of sample size is    “What should be my sample size?” The article by Isreal (2013) provides you a summary of the most important points that one needs top consider to answer such a question.

In fact ,you need to consider a number of factors to determine the appropriate sample size. These include , the purpose of the study, population size, the level of precision, the level of confidence or risk, and the degree of variability in the attributes being measured. For full discussion of these issues, Read the article below  DETERMINING SAMPLE SIZE. It discusses all these factors and how to use published tables, and applying formulas to calculate a sample size.

Article: Determining the sample size 
More precision, more sample size
The table below provides sample sizes for different sizes of population at a 95% confidence level and margin of error ranging from 5% to 1%. Note that the smaller the margin of error ( which means when we need more precise measurement of the variable ) , we need to have more sample size.
