With this method some respondents have a higher chance of becoming part of the sample. This is the minimum sample size you need to estimate the true population. These are the types of non-probability sampling.
You just need to provide the population proportion p p the sample size.

Choose the required confidence level from the dropdown menu. Dont just take a guess at how many people should take your survey and dont get bogged down in probability sampling or probability distribution modelsuse our sample size calculator. Calculate the probability that the sample variance of a random sample of size n 5 from a Normal population with σeq2 eq 25 will be between 20 and 30.
