Bersoft Sampling Analyzer (BSA) is intended for simulating and analyzing samplings from experimental data, using both infinite and finite populations. BSA allows to filtering the population for identifying and generating subpopulations or choosing the best set of data range the population. BSA supports basic statistics, frequency and graphics that are available for both the population data and simulated samples data. Calculating the sample size BSA provides several formulas for getting the sample size. The population size will affect the sample size especially if the population is not too large.
