Recover frequency from GRP

Optional numerical practice

Extra drills; no claim that these exact questions or allocated marks appeared in TEE

Optional practice question. A campaign delivers 180 GRPs and reaches 60% of its defined target. Calculate average frequency. [2 practice marks]

Answer

Authored illustration: these numbers were chosen to explain a faculty-note concept. No matching supplied-data question was found in the 14 recovered APR papers. Standalone calculation drills are optional practice; their marks are author-set.

Given

GRPReach
18060%

To find

Average exposures per reached person.

Formula and why

\text{GRP}=R_{\%}\bar f\quad\Rightarrow\quad\bar f=\frac{\text{GRP}}{R_{\%}}LaTeX: \text{GRP}=R_{\%}\bar f\quad\Rightarrow\quad\bar f=\frac{\text{GRP}}{R_{\%}}

Divide both sides of the GRP equation by reach percentage. Use 60 here, not 0.60.

Step-by-step solution

Step 1. Write the substitution

\bar f=180\div60LaTeX: \bar f=180\div60

Step 2. Carry out division

\bar f=3LaTeX: \bar f=3

Final answer: Average frequency = 3.
