These notes are heavily based on the following books. Given data, the most standard measures are: Sample mean (often simply called the mean) is the average value Median describes the center of the data set when the data is ordered by value If n is an odd number, there is exactly one data value lying at the center of the . . Hypothesis Test Outcomes There are two possible outcomes to a hypothesis test. Two functions can be compared for There are two di erent approaches for estimating: Point Estimation and Interval Estimation.

Definition: Inferential statistics is a statistical method that deduces from a small but representative sample the characteristics of a bigger population.
