Population, sample, and good data

Population, sample, and good data

Population shown as a large group, sample as a highlighted subset, strata boxes, and a numbered list with every fifth member selected from a random start

In statistics, the population is the whole group we want information about, while a sample is the smaller group we actually collect data from. A census means collecting data from every member of the population.
