Ratings across insertions

Optional numerical practice

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

Optional practice question. An advertisement is inserted twice in a programme with a rating of 12 and three times in a programme with a rating of 8. All ratings use the same target universe. Find total GRP. Can unique reach be inferred? [3 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

To find

Total GRP and whether unique reach is known.

Formula and why

\text{GRP}=\sum_j (\text{rating}_j\times\text{insertions}_j)LaTeX: \text{GRP}=\sum_j (\text{rating}_j\times\text{insertions}_j)

Each insertion contributes its rating points. Audience duplication between insertions remains in GRP.

Step-by-step solution

Step 1. First programme contribution

12\times2=24LaTeX: 12\times2=24

Step 2. Second programme contribution

8\times3=24LaTeX: 8\times3=24

Step 3. Add rating points

24+24=48\text{ GRPs}LaTeX: 24+24=48\text{ GRPs}

Step 4. Assess what is missing

Unique reach cannot be determined: the overlap between the audiences is not supplied.

Final answer: 48 GRPs; insufficient information for unique reach.
