Exam 10: The Chi-Square Test and Measures of Association

Suppose you obtain a chi-square statistic of 3.86.Are your results statistically significant if the critical value obtained from the distribution of chi-square is 6.63 with an alpha level of .01?

Below are hypothetical data on the relationship between sex and marital satisfaction.Calculate the expected frequencies,or the frequencies we would expect to observe if there were no relationship between sex and marital satisfaction.

A researcher is examining the relationship between job security and job satisfaction.Use the data below to calculate the value of gamma.

Lambda may range in values from 0.0 to ±1.

In order to determine the statistical significance of the chi-square statistic,you need to know the number of cells in the table for which the expected frequencies are free to vary given that the marginal totals are already set.What is the statistical name for this quantity and how is it calculated?

The number of degrees of freedom in a cross-tabulation data with three rows and four columns is 12.

When two variables are not associated,they are said to be statistically dependent.

A gamma of -1.0 indicates a perfect,negative association between the variables.

In a bivariate table,two variables are said to be statistically independent when,within each category of the independent variable,the percentage distributions of the dependent variable are

What interpretation do we get if Kendall's Tau-b reaches a value of 1?

Chi-square is a useful test for determining ______ significance but not for determining ______ significance.

The stronger the relationship between the variables,the larger will be the reduction in the number of errors of prediction.
