Sample calculation

The online calculator will help you determine how many respondents need to be surveyed with acceptable accuracy so that their opinion can be extrapolated to the entire population. The advantage of the formula used here is that a correction for small populations is automatically introduced. Sample – part of the objects of the population, acting as objects of observation, selected from the population for participation in the study using a specific procedure. The sample must be representative (equally represented), i.e., correspond to the characteristics of the population as a whole. Representativeness determines how possible it is to generalize the results of the study with the involvement of a specific sample to the entire population from which it was collected.
