How to calculate ratings and how to calculate ratings?

Viewership survey data consists of two parts. Part of it is the background data of the respondents (the individuals surveyed and the households to which they belong), including gender, age, occupation, education level, personal household income, individual household assets, family size, family role relationship, household viewing equipment and television reception, basic life attitude and leisure choices, work situation, residential area, language used, etc. This part of the data is mainly obtained through the sample household network access survey, which becomes the background data for rating calculation and analysis.

The other part is the TV viewing data of the respondents recorded through the diary method or the personnel meter method, which is the recorded information of each member of the household (sample household) with television (respondents aged 4 years and above) who watches or does not watch TV every 15 minutes (per minute for the person meter) and what channels they watch for 24 consecutive hours every day.

In addition, there is a part of the data that does not belong to the ratings survey data, that is to say, it is not the data obtained from the sample household survey, but it is also very important for the calculation and analysis of ratings, which is the data of the electric channel attribute and the broadcast data of TV programs. This data is generally provided by television stations or obtained through television monitoring.

With the above three parts of the data, it is possible to calculate the ratings metric. Based on TV viewing data alone, the total ratings and the ratings of the sub-channel can be calculated; If the background data is combined, the audience rating of the target audience can be calculated; If you combine TV program broadcast data, you can calculate program ratings. Combining this data in this way, a range of viewership metrics can be calculated.

Gross Rating Points (GRPS): The sum of the ratings of each break in an advertising campaign;

Huts Puts (Household People Using Television): The average percentage of TV turned on by household or per person (regardless of channel) in a given time period;

Reach: The cumulative percentage of viewers who watch a series of programs or a certain ad schedule at least once;

Frequency: The average number of times viewers watch an ad schedule or series of programs;

Audience share: The percentage of viewership of a particular channel or program to the total viewership of a given time period.

The TV station randomly contacted thousands of people in the most convenient interpersonal circles.

Look at the ratings, and then use your imagination to try to get the hype out.

Ratings The number of people in the area who tune in to the show (households) The total number of people in the area (total households).

1. There are two methods of ratings data collection, namely the diary card method and the personnel meter method.

The diary card method is a method in which all family members aged 4 and above in the sample household record the channels and time periods of TV they watch every day on the diary card at any time to obtain the viewing information of TV viewers.

The measuring instrument method is a method of using a measuring instrument to record in detail the TV viewing of all family members aged 4 and above in the sample town, so as to obtain the viewing information of TV viewers.

2. Ratings statistics:

Survey agencies (generally independent research agencies, but also TV stations do their own) select some users according to the sample distribution, pay Yuming to install some "monitoring equipment", which is used to record the user's change of channels, and regularly collect these data to make ratings statistics.

Real-time ratings surveys are generally obtained by searching for designated users, which is faster, because it is not a random survey, but a contracted and pre-selected designated user according to the sample distribution.

At the same time as the TV audience survey was conducted, ** TV stations and some local TV stations began to carry out ratings statistics.

Although China's ratings survey started late, it has developed rapidly, and it only took a dozen years to complete the development process of more than half a century in the developed countries of the West.
