The basis of analysis for the chi-square test is a(n)_____ table (also called a frequency or crosstabulation table).
A)expected frequency
B)cellular
C)summary
D)contingency

Question

Quizplus · Accepted Answer

The chi-square test is used to compare the observed frequencies in a contingency table to the expected frequencies, based on the assumption of independence between the variables. Therefore, the basis of analysis for the chi-square test is a contingency table, which shows the frequencies of the different categories or levels of two or more variables. A contingency table is also called a frequency or crosstabulation table, and it organizes the counts of a categorical variable in rows and another categorical variable in columns. The cells of the table represent the frequency or count for the combination of the levels of the two variables. Therefore, the correct answer is D, contingency table, as it is the most appropriate and specific term to describe the type of table that is required for the chi-square test. The other options, expected frequency, cellular, and summary, could be related to specific aspects or components of the contingency table, but they do not represent the overall or essential characteristic of the table.
