In a pic chart, each slice of the pic corresponds to the relative frequency of a class of the qualitative variable.2.4 First, we find the frequency of the grade A. The sum of the frequencies for all 5 grades mus Methods for describing sét of SMt be 200. Therefore, subtract the sum of the frequencies of the other 4 grades from 200. The frequency for grade A is:200 - (36 + 90 + 30 + 28) = 200-Methods for describing sét of SM
184 = 16To find the relative frequency for each grade, divide the frequency by the total sample size, 200.
