      In this case, all you have to do is decide on the confidence level (90 per cent or 95 per cent) and interval (5 per cent to 10 per cent) and the calculator gives you the required sample size according to the population size. Once calculated, the sample size should be increased by 20 per cent. This is done as it is likely that some of the ...

      Sample size determination for descriptive studies is based on confidence intervals; that is, the level of precision required in providing estimates of the rates, proportions and means. Comparative studies include case-control designs, randomized clinical trials, etc. where a comparison between two or more groups is the key analysis.

      The stated confidence level of a one-sample t interval for μ is exactly correct when the population distribution is exactly Normal. No population of real data is exactly Normal. The usefulness of the t procedures in practice therefore depends on how strongly they are affected by lack of Normality.
