Exam 11: Bivariate Association for Nominal- and Ordinal-Level Variables

For variables measured at the ordinal and interval-ratio levels, measures of association will have a lower limit of _______ and an upper limit of ________

To compute Spearman's rho, we

A bivariate table shows the association between gender and whether or not a person ever attends formal religious services. Lambda was .34. What may be concluded?

For the same bivariate table, Cramer's V is .27 and lambda is zero. What can we conclude?

For a 3 x 3 table, the appropriate chi square based measure of association would be

Tests of significance and measures of association provide information about sample data that is

For the relationship between social class and movie attendance, a researcher found a gamma of - 0.45. This relationship is

In a bivariate table, the categories of the dependent variable are placed in the

With the independent variable in the columns, the "maximum difference" is the largest difference

While ignoring the independent variable, we make 78 errors when predicting the dependent variable. When taking the independent into account, we reduce the number of errors to 43. Therefore

Like lambda and gamma, Spearmans' rho can be interpreted by the logic of

In the case of a perfect association, predictions from one variable to another can be made

For variables measured at the nominal level, measures of association will have a lower limit of _______ and an upper limit of _______

A researcher has computed a gamma of -0.45 between marital happiness and number of children. What can she conclude?

Lambda compares the number of errors of prediction under two separate rules. In the first rule, the independent variable is

When variables vary in opposite directions, the association between variables is said to be

Gamma provides a summary measure of the

For ordinal level variables with only a few categories or values, an appropriate measure of association would be

A researcher tested the relationship between gender and support for assisted suicide ("death with dignity") and found a Cramer's V of 0.45. This relationship is

"As the temperature rises, the crime rate increases."
