Document Summary
The average of the data is statistically known as central tendency. There are a few ways to calculate central tendency. Population vs sample terms (this is very important in the future): Parameter is a measure of the population (both start with p) Statistic is a measure of a sample (both start with s) There are two arithmetic mean terms, one for population and one for sample. The population arithmetic mean is (pronounced mew if you"re typing hold the alt key and type 230) because it deals with population, it is a parameter.
