When counting ratings, how to determine the number of users watching a certain program

At present, there are two methods of rating data collection, namely the diary method and the personnel meter method. The diary method refers to the method of collecting viewing information by filling out diary cards by all family members aged 4 and above in the sample household. Each household member in the sample had their own diary card, and they were asked to record their daily TV viewing (including the channels they watched and the time slot) on their diary card at all times.

The time interval listed on the diary card is 15 minutes. Each diary card can record the viewership for a week.

The personnel measuring instrument method refers to the method of using the "personnel measuring instrument" to collect TV viewing information, and it is the latest international ratings survey method. Each member of the sample family had their own button on the handset, and there was also a guest's button. When a family member starts watching TV, they must first press the button on the handset that represents themselves, and then press the button when they are not watching TV.

The measuring instrument will store all the information of watching TV in a time period of minutes (even accurate to the second), and then transmit it to the central computer of the headquarters through the ** line (or through the handheld computer to access the data).

How long will it take for the ratings to come out? Some are for a week, some are two weeks, and some are for a day. Liu Yannan said that it mainly depends on what kind of measurement method is used, if the diary method is used, because to collect and analyze the data, it takes a week at the earliest, and generally two weeks; If the personnel measuring instrument method is adopted, because the first line can return the data in real time, it can provide ratings data every other day, but the cost of the personnel measuring instrument is relatively high.

If the diary method is used, because it takes one week to collect and analyze the data at the earliest, it generally takes two weeks, which obviously has a certain lag, and it is not optimistic in terms of accuracy; If the personnel measuring instrument method is adopted, because the first line can transmit data back in real time, it can provide ratings data every other day or even faster in the world, and the cost of the measuring instrument is naturally relatively high.

Computer automation statistics, for example: you turn on WIF, if there are other users connected, it will be displayed, and then you set up an automation program on the computer to sum all the users connected to your wifi, so, ratings = the number of all connected users The maximum number of users. The maximum user capacity is the maximum number of users allowed to connect to your WiFi.

How do you determine the number of users watching a show? In the era of digital TV, you can count every channel you see.

In fact, the statistics are inaccurate, but everyone uses this method, so this method is relatively accurate.

As an important quantitative indicator in the era of "attention economy", it is the scientific basis for in-depth analysis of the TV ratings market, an important reference for program production, arrangement and adjustment, the main indicator of program evaluation, and a powerful tool for formulating and evaluating media plans and improving advertising efficiency.

Although the ratings themselves are just a simple number, behind the seemingly simple numbers is a complex process of scientific basic research, sampling and establishment of fixed sample groups, measurement, statistics and data processing.
