Document Summary
Measures of central tendency- the most common way of describing a set of observations is by identifying the measure of central tendency. It is a numerical value that summarizes a set of observations into a single value. Population mean- if the set of data x1 , x2 , , xn, not necessarily all diverse represents a finite population of size n. Sample mean- if the set of data x1 , x2 , , xn , not necessarily all distinct represents a finite sample of size n.
