$\mathrm{A}$table is a classification tool that reveals the various possibilities in the comparison of variables.
Information obtained on variables measured at the nominal or ordinal level is said to be data.
frequencies are the frequencies presented in the cells of a table.
The frequency is the frequency that would be expected to occur in a particular cell, based upon chance and the marginal distributions.
The equation for expected frequency for the chi-square test of independence is
The equation for degrees of freedom for the chi-square test of independence is
