Abu-Bader Sample Size App helps users to determine the minimum sample size required for the most utilized bivariate and advanced statistics The Sample Calculator answers one of the most frequently asked questions in statistics: What size sample do I need?

You provide the estimated For example, if the study population involves 10 people in a room with ages ranging from 1 to , and one of those chosen has an age of , the next person chosen is more likely to have a lower age. The finite population correction factor accounts for factors such as these. Refer below for an example of calculating a confidence interval with an unlimited population.

Sample size is a statistical concept that involves determining the number of observations or replicates the repetition of an experimental condition used to estimate the variability of a phenomenon that should be included in a statistical sample. It is an important aspect of any empirical study requiring that inferences be made about a population based on a sample.

Essentially, sample sizes are used to represent parts of a population chosen for any given survey or experiment. The equation for calculating sample size is shown below. EX: Determine the sample size necessary to estimate the proportion of people shopping at a supermarket in the U. Assume a population proportion of 0. Refer to the table provided in the confidence level section for z scores of a range of confidence levels.
