Exam-answer use: Reach, Frequency and Message Weight were asked together in May 2026 Q4(a) [10 marks], with calculation examples. The links below distinguish faculty-note examples from extra drills.

## Formula



$$
R_{\%}=\frac{n}{N}\times100
$$



n = distinct target members reached at least once; N = total target population. Divide the reached part by the whole target. Repeated exposures do not create new people.

#### Illustrative example · Read the calculation in words

For 3,000 distinct people out of 10,000: 3,000 ÷ 10,000 = 0.3; 0.3 × 100 = 30%.
