Work out relative frequency instantly with clear inputs, formula shown and shareable results.
Relative frequency divides each class count by the total, giving proportions that always sum to 1. Expressed as percentages they make distributions with different sample sizes directly comparable.
Relative frequency
rᵏ = fᵏ / Σf
The total is 60, so the third class has relative frequency 22/60 ≈ 0.3667, that is 36.67%.
Yes, exactly, since every observation belongs to precisely one class.
