Sal uses the contingency table chi-square test to see if a couple of different herbs prevent people from getting sick. Which test. There are three ways to compute a P value from a contingency table. Fisher’s test is the best choice as it always gives the exact P value, while the chi-square test only calculates an approximate P value. For example, Table 1 shows the data from the Mediterranean Diet and Health case study.
Sampling Scheme 1: The total number of data values in the contingency table (N) is fixed, but none of the row or column totals are fixed. To produce the plot shown in Example of a Contingency Table, follow the instructions in Example of Contingency Analysis. Example of a Contingency Table. Analysis of risk factors for unfavorable outcomes (odds ratio, relative risk, difference in proportions, absolute and relative reduction in risk, number needed to treat). Quantities Derived from the 2-by-2 Contingency Table.
A contingency table is essentially a display format used to analyse and record the relationship between two or more categorical variables. It is the categorical equivalent of the scatterplot used to analyse the relationship between two continuous variables. Contingency Table Analysis. Methods and Implementation Using R. Pages 17-61.
