E)comparing the pie chart with the stacked bar chart

Question

Quizplus · Accepted Answer

The chi-square test is performed by comparing the observed frequency with the expected frequency, which can be calculated based on a null hypothesis. The test is commonly used to determine the significance of the association between two categorical variables. Therefore, comparing a metric variable with a categorical variable, comparing one frequency table with one cross-tabulation table, comparing the difference among categories of more than three variables, comparing the pie chart with the stacked bar chart do not accurately describe the chi-square test.
