In this case, we could choose any of the three. However, the ... WebThe most common measure of magnitude of effect for two binary variables is the phi coefficient. Phi can take on values between -1.0 and 1.0, with 0.0 representing complete independence and -1.0 or 1.0 ... estimate the association between two underlying normal variables and can be used for any I × J table. 1 The phi coefficient may be ...
WebFeb 4, 2024 · The absolute value of the phi statistic is the same as Cramer's V for a 2 x 2 table. Unlike Cramer's V, phi can be positive or negative (or zero), and ranges from -1 to 1. When phi is close to its extremes, or with small counts, the confidence intervals determined by this method may not be reliable, or the procedure may fail. References WebA 2x2 table means that subjects are separated based on two factors (or questions) with two levels in each factor (groups 1 or 2 for the first factor and outcome 1 or 2 for the second factor). Each subject falls into one of the two levels for each factor, which results in four possible categories in all.
