Hypothesis Testing

Hypothesis testing is used to determine if an assumption about a set of data is true.  Ideally, you would conduct statistical analysis on the entire population.  Since this is near impossible, a random sample data set of the population is examined against an assumption.

There are two types of hypothesis:

Null Hypothesis (Ho)

Alternate Hypothesis (Ha)

Ho assumes that there is no difference in the hypothesis while Ha states that there is a difference or relationship in the hypothesis.
