Conducting Cross Tabulation Analysis Construct the Cross-Tabulation Data Calculate the Chi-Square Statistic, Test the Null Hypothesis of No Association NO No Association Reject H 0? YES Determine the Strength of Association Using an Appropriate Statistic Interpret the Pattern of Relationship by Calculating Percentages in the Direction of the Independent Variable MNH, MKT 416, HYPO

Example of Cross Tabulation Internet Usage Male Female Row Total Light 5 10 15 Heavy 10 5 15 Column Total 15 15 MNH, MKT 416, HYPO
