7-9 Tests

The following is a list of tests, and a description of what each one tests for.

	Test Name	Description
Z Test		The Z Test provides a variety of different tests based on standard
		deviation based tests. They make it possible to test whether or not
		a sample accurately represents the population when the standard
		deviation of a population (such as the entire population of a
		country) is known from previous tests.
	1-Sample Z Test	Tests a single sample mean against the known mean of the null
		hypothesis when the population standard deviation is known.
		The normal distribution is used for the 1-sample Z test.
	2-Sample Z Test	Tests the difference between two means when the standard
		deviations of the two populations are known.
		The normal distribution is used for the 2-sample Z test.
	1-Prop Z Test	Tests a single sample proportion against the known proportion of
		the null hypothesis.
		The normal distribution is used for the 1-Prop Z test.
	2-Prop Z Test	Tests the difference between two sample proportions.
		The normal distribution is used for the 2-prop Z test.
t Test		Used instead of the Z Test when the population standard deviation
		is unknown.
	1-Sample t Test	Tests a single sample mean against the known mean of the null
		hypothesis when the population standard deviation is unknown.
		The t distribution is used for the 1-sample t test.
	2-Sample t Test	Tests the difference between two means when the standard
		deviations of the two populations are unknown.
		The t distribution is used for the 2-sample t test.
	Linear Regression t Test	Tests the linear relationship between the paired variables (x, y). The
		method of least squares is used to determine a and b, which are the
		coefficients of the regression formula y = a + bx. The p-value is the
		probability of the sample regression slope (b) provided that the null
		hypothesis is true, = 0.
		The t distribution is used for the linear regression t test.
2 Test		Tests the independence of two categorical variables arranged in
		matrix form. The 2 test for independence compares the observed
		matrix to the expected theoretical matrix.
		The 2 distribution is used for the 2 test.
2-Sample F Test		Tests the ratio between sample variances of two independent
		random samples.
		The F distribution is used for the 2-sample F test.
