Rejects the null hypothesis when it is actually true. This is a false positive.
Regardless of how your data is distributed, if you take the mean of several samples and plot them, the resulting curve will be approximately normal.
How close your samples are to each other.
This property of a test gives the probability against committing a Type II Error.1-β
Indicates the proportion of the variance of one variable that is predictable from the other variable.
Gives the measure of the center of the distribution of a variable. In most cases it is figured as a weighted average,E(Y) = ∑yP(y)
When data is not symmetric about the mean.

Number of ways to choose r objects from a group of n. Order does not make a difference.(n!)/r!(n-r)!
Fails to reject the null hypothesis when it is actually false. This is a false negative.
Means you have two different criteria to meet, but one of them is already given.
This given outcome translates form the experimental normal curve to the normal curve with a mean of zero and stand deviation of one. z = (x-μ)/σ
Gives a measure of how closely correlated the two variables are.
Number of arrangements of r objects from a group of n that are possible. Order makes a difference.(n!)/(n-r)!
