Fill in the missing values. Relative Frequency = Frequency / sample size. Frequency = Sample size * Relative Frequency Also useful: 15% = 15 * (1/100) = 0.15 and: 0.004 = 0.004 *100% = 0.4% n= Grade Frequency Relative frequency A 11 % B 14 % C 11 % D 6 % F 8 % When you add up the numbers in the relative frequency column the sum always equals %. When you add up the numbers in the frequency column the sum always equals (the notation) which in this case equals [n50]. If passing is considered a grade of A,B, or C, how many students passed? .
