Chi square phi and cramer's v
WebIt is also common to observe that when there appears to be a very low probability associated with a chi-square outcome, the phi-coefficient may also appear to demonstrate a low estimate. The formula for the phi coefficient is: ϕ2 = χ2 n = ϕ= √χ2 n ϕ 2 = χ 2 n = ϕ = χ 2 n. In the chi-square example shown in the previous chapter and in ...
