– Average Frequency = 150/30 = 5

of that audience is called efficiency or CPM (Cost
per thousand) and CPR (Cost per rating point)
• CPM – used to measure one media vehicle
against a similar media vehicle e.g. one magazine
against another magazine
• CPR – Comparing media vehicles based on their
ratings

e.g. CPM = 50,000/60,000 *1000 = 833.33
• CPR = Cost of message unit / Rating
e.g. 70,000/15 = 4666.66
