Sample Size Calculator



Sample Size Calculator is an online Probability and Statistics tool for data analysis programmed to calculate the percentage of sample size. This calculator generate the output values of size according to the respective input values of confidence level, confidence interval and population

Definition

Sample size determination is strongly associated to statistical estimation. The sample size of a statistical experiment is the number of observations that comprise it. It is typically denoted n and a positive integer. The sample size is a key feature of any experimental study in which the objective is to make assumption about a population from a sample. According to the three values such as maximum error of estimate, the population standard deviation, and the degree of confidence, the sample size provide the answer for the question How large a sample is necessary to make an accurate estimate? The sample size is derived from the maximum error of estimate and can be calculated from the mathematical formula
