For example, if you expect to lose about 20% of the sample, then the sample size should be increased by a factor of 1 / (1 - 0.2) or 1.25. That is, enroll 25% more subjects that the sample size вЂ¦

That said, I agree with the majority of the people posting here that a sample size of 20 is too small for most practical purposes. Because of the large standard errors associated with such a small

So you will have to calculate sample sizes per hospital. This of course will make your required total sample size considerably higher than when you only want to look at a total level. You could also group hospitals per region and compare regions if you want to put a limit on your sample size.

What is a sample size? A sample size is the total number of data points collected in a study (e.g., the number of responses to a single survey question). Identifying sample size is key to determining whether data accurately reflects the population as a whole.
