Chi Square Calculator for 2x2 This simple chi-square calculator tests for association between two categorical variables - for example, sex (males and females) and smoking habit (smoker and non-smoker). Chi-Square Calculator Requirements Random sample...
The df for association chi-squares is defined as: df (or ν) = (R - 1)(C - 1) Since there were two rows and three columns in the example data, there is df = (2 - 1)(3 - 1) = 2. 7 Version: 10/14/2013 14. Testing H 0 To statistically test the tenability of...
小样本就用Fisher's exact test for small cell sizes 大样本就用Chi-Square Test 首先画一个2X2的表格 首先就可以算一个OR,就是比例的比例 = a * d / b *c = (a/b) / (c/d),越接近1就越代表没有区别,即没有关联(两个变量随机)。 其次可以用R来算P-value 1 2 3 4 tmp.table <-matrix(...

I thought it was an extension of McNemar test for the case of tables greater than 2X2. Reply Sabrina says July 15, 2016 at 10:39 am Hi, I was wondering whether either of these tests would be appropriate for assessing the association between repeat questions which were inserted into a ...
What is the main difference between independence test and test of homogeneity (chi-square)? What is the difference between the chi-square test for 2x2 table and Fisher's exact test; under what circumstance do you use each test? a. What are the three uses of ...
