A stepped rule of thumb is a number that depends on a limited amount of information about the main study such as the required power or the relative value of the effect size. The stepped rules are based on the NCT approach discussed by Whitehead et al. (2016). These two categories have ...
Motivated by an engineer's question to understand the "Rule of 7" sample size rule of thumb, this article studies the statistical properties for a sample size of 7 and well as other sample sizes. Properties of ranges, tolerance intervals and confidence intervals, are considered. Sample size ...

To date most translation/adaptation/validation studies have used just 100 patients, presumably based on the 'rule of thumb' sample size established by Martin and Allan (6) see for example Su, Yang (3), Kuo, Chen-Sea (8) Kuo, Ma (25). Minimum Sample Size Requirements for a Validation ...
adjusted appropriately to take dropouts into account. Empirical results support the conclusion that, whatever reasonable level of power would be provided by a given sample size in the absence of dropouts, essentially the same power can be realized in the presence of dropouts simply by adding to ...

A sample size that is too large will result in wasting money and time. It is also unethical to choose too large a sample size. There is no certain rule of thumb to determine the sample size. Some researchers do, however, support a rule of thumb when using the sample size. For examp...
