Chi-Square, Cramer's V, and Lambda for a Rows by Columns Contingency Table
| º | perform a chi-square analysis [the logic and computational details of chi-square tests are
described in Chapter 8 of Concepts and Applications]; | ||
| º | calculate Cramer's V, which is a measure
of the strength of association among the levels of the row and column
variables [for a 2x2 table, Cramer's V is equal to the
absolute value of the phi coefficient]; | ||
| º | and calculate the two asymmetrical
versions of lambda, the Goodman- Kruskal index of predictive association,
along with some other measures relevant to categorical prediction. |
