Question

GRPs, reach, and frequency are mathematically related in the following ways:

            GRPs               = Reach x Frequency

            Reach              = GRPs / Frequency

            Frequency      = GRPs / Reach

Fill in the blank. Keep format the same for each answer.

Reach is expressed to the closest whole number and use a % sign

Frequency is expressed to the closest tenth.

GRP are expressed to the closest whole number...no % or decimal..

Find the missing values in the chart. The boxes 1-6 are where you place the missing value on that line. So box 1. is for the answer to line 1 which is a GRP value

Explanation / Answer

Reach is the number/percent of different homes/persons exposed at least once to an advertising schedule so it is while number with a % sign it is a whole number. Frequency is closest tenth so

1. GRPs = 55*4.6= 253

2. Reach = 259/3.7= 70

3. Frequency= 450/63 = 7.143 in closest tenth = 7.1

4. Reach = 325/5.4= 60

5. GRPs= 72*6.1=439

6. Frequency= 600/51= 11.7647 in closest tenth = 11.8
