WebThe theorem leads us to the following strategy for finding probabilities P ( z < X < b) when a and b are constants, and X is a normal random variable with mean μ and standard deviation σ: 1) Specify the desired probability in terms of X. 2) Transform X, a, and b, by: Z = X − μ σ. 3) Use the standard normal N ( 0, 1) table, typically ... Webthe one-tailed probability would be the sum of the separate probabilities for the arrays And the two-tailed probability would be that sum plus the sum of the separate probabilities for the arrays of equal or greater disproportion at the other extreme: two-tailed probability = 0.01852 + 0.00449 = 0.02301 Return to Top ©Richard Lowry 1998- 2024

WebFor two metric variables, a Pearson correlation is the preferred measure. If both variables are dichotomous (resulting in a 2 by 2 table) use a phi coefficient, which is simply a Pearson correlation computed on dichotomous variables.
