Identify two important operating standards that are routinely measured in your organization. These measures must meet the criteria for qualitative, nominal measures. Observations must be cross-classified into a contingency table. Obtain a sample that will produce at least five observations into each group of the cross-classification.
Purpose: To demonstrate the application of non-parametric tests in your organization.
Example: A standard measure that fits these requirements is the human resource department's employee tracking system. The director of human resources of my company wants to do a study to determine if there is a relationship between the management status and gender of the employees. She creates a contingency table that has Male or Female categories for the rows, and Manager or non-manager categories for the columns. Then she counts the number of female managers, female non-managers, male managers, and male non-managers and enters the numbers in the table. This is the observed value table. Then she conducts the hypothesis test.
Perform the cross-classification of the two nominal variables into a contingency table.
Test the hypothesis that there is no relationship between the two variables.
Discuss the result and interpretation of your hypothesis test.

The trend line y = 0.70 + 0.005t was calculated from quarterly data for 1999 -2003, where t = 1 for the first quarter of 1999. The seasonal indexes computed from the trend line for the four quarters of the year 2004 were .85, 1.05, 1.15, and .80, ..
