Short exam answers with examples

### Practice question. Distinguish reach and frequency. [2 practice marks]

#### Answer

**Reach** is the number or percentage of distinct target members exposed at least once. **Average frequency** is the average number of exposures among those reached during the same period.

#### Illustrative example · Same audience, repeats

If 100 distinct people generate 300 impressions, reach is 100 people and average frequency is 300 ÷ 100 = 3. A percentage reach also requires the target population.
