We can"t determine if the next coin flip will be heads or tails. Add up all numbers and divide by the amount of numbers. Techniques used to condense and describe sets of data. Major techniques are frequency table, histogram, and summary numbers. Techniques used to systematically draw conclusions about a population from a set of sample data. The goal is generalization of information about a sample to information about a population.
