WebThe multiplicative inverse of a number x is given by x -1, such that when it is multiplied by its original number, it results in value equal to 1. For example, the multiplicative inverse of 2 is 2 -1 as it satisfies the expression: 2 x 2 -1 = 2 x ½ = 1 It is also called as reciprocal of a number. What is the multiplicative inverse of 13?

Phi Coefficient (Mean Square Contingency Coefficient)

WebThe range of it is between -1 and 1 for 2-by-2 tables, and is between 0 and min (sqrt (R-1), sqrt (C-1)). Computationally, phi is the square root of chi-square divided by n, the sample size. The phi coefficient is often used as a measure of association in 2-by-2 tables formed by true dichotomies. WebThe most commonly used effect size measure associated with the 2 × 2 chi-square test is phi, φ (the Greek lower case "fee", as pronounced by statisticians). Phi is a simple computation, based on chi-square. ... tables (e.g., a 2 × 2 from a 5 × 3 design; Delucchi, 1993). Such tests may involve marginal proportions or
