What’s the difference between a radio daypart half-hour average audience and a radio daypart cume?
The “radio daypart cume” captures everyone who listened to a half-hour or more of radio during a given daypart. This is determined by “orring” together everyone who listened to a single half-hour, two half-hours, etc. of the daypart. The “half-hour average audience” is the average number of people who listened to the radio during a single half-hour in that daypart; it is computed by calculating the total number of half-hours listened to and dividing that by the total number of daypart listeners.
