Contingency table percentages calculator12/2/2023 Note that the expected values for each combination is big(69.6, 75.4, 50.4, 54.6) so the assumption is met and conclusions are sound. With a big p-value of 0.2381 we do not reject the hypothesis so gender and opinion is not associated. A list of tests are performed where the first one is the classic Chi-square test. The results include a contingency table with observed and expected values. Likelihood Ratio Chi-Square 1 1.3926 0.2380Ĭontinuity Adj. Statistics for Table of opinion by gender The "weight" statement tells the precedure how many subjects there are for each combination of gender and opinion. The "chisq" option requests a chi-squre test, and "nocol", "norow", "noprecent" simplify the output and "expected" requests the expected values. Tables opinion*gender / chisq nocol norwo nopercent expected The counts can be inputed and analyzed as below. Then one can use the counts, rather than the original data files to run the contingency test. The easiest way to carry contingency test is when counts are availiable for each categories, for example, if the frequencies are given below, On the other hand, if the female and male are dependent (as in husbands and wives), the McNemar's test should be used. Samples must be independent, for example, when checking the gender (Female/Male) effect with some opinions (yes/no), the female and male must be independently selected.No more than 20% of the expcted value for each cell is less than 5, otherwise Fisher's exact test(discussed at the end) should be used.It is usually used to check relationship between two variables. Output, interpretation and assumption checkingĬontingency table test is used when both dependent and independent variables are categorical.Analyzing comprehensive questionanir data with contingency test, without knowing the counts.Analyzing simple data with contingency test, if knowing the counts.Contingency procedure demonstrated with an example
