expected frequency

a frequency predicted from a theoretical model. For example, a university administrator may want to examine the observed frequency of female and male students and compare it to the expected frequency for each gender to determine how similar the pattern is to that in the general population. Expected frequencies are chiefly used in the chi-square test.
