Methods and apparatus to create a panel of media device users

1. At least one non-transitory machine readable medium comprising instructions which, when executed, cause a machine to at least:

provide monitoring instructions to a media provider for creation of an instrumented application;

receive a unique identifier and an application identifier from a media device executing the instrumented application, the unique identifier and the application identifier received without collecting personally identifiable information;

create a master frame corresponding to media devices that have executed the instrumented application;

sort the master frame based on at least one of a date of installation of the application at the media device, an identifier associated with the application installed at the media device, or a number of instrumented applications installed on the media device;

assign the media device from the master frame into a first test cell based on a skip rate;

select a first recruitment interface associated with the first test cell, the first recruitment interface different from a second recruitment interface associated with a second test cell; and

instruct the instrumented application to, in response to the instrumented application being executed for a first time after a threshold period of time since an initial execution of the instrumented application has elapsed, display the first recruitment interface to a user associated with the media device requesting the user to join a panel.

2. The at least one non-transitory machine readable medium of claim 1 , wherein the instructions, when executed, further cause the machine to receive monitoring data from the instrumented application after the user has agreed to become a panelist.

3. The at least one non-transitory machine readable medium of claim 1 , wherein the instructions, when executed, further cause the machine to generate the unique identifier to be used by the media device.

4. The at least one non-transitory machine readable medium of claim 3 , wherein the instructions, when executed, further cause the machine to transmit the unique identifier to the media device.

5. The at least one non-transitory machine readable medium of claim 1 , wherein the application identifier is assigned to the instrumented application by at least one of the media provider or an application developer.

6. The at least one non-transitory machine readable medium of claim 1 , wherein the assigning of the media device to into the first test cell is further based on a random value, wherein the random value is less than or equal to the skip rate and greater than or equal to zero.

7. The at least one non-transitory machine readable medium of claim 1 , wherein the skip rate is based on a count of media devices in the master frame divided by a desired number of media devices for the panel.

8. A method for creation of a panel, the method comprising:

providing monitoring instructions to a media provider for creation of an instrumented application;

receiving a unique identifier and an application identifier from a media device executing the instrumented application, the unique identifier and the application identifier received without collecting personally identifiable information;

creating a master frame corresponding to media devices that have executed the instrumented application;

sorting the master frame based on at least one of a date of installation of the application at the media device, an identifier associated with the application installed at the media device, or a number of instrumented applications installed on the media device;

assigning the media device from the master frame into a first test cell based on a skip rate;

selecting a first recruitment interface associated with the first test cell, the first recruitment interface different from a second recruitment interface associated with a second test cell; and

instructing the instrumented application to, in response to the instrumented application being executed for a first time after a threshold period of time since an initial execution of the instrumented application has elapsed, display the first recruitment interface to a user associated with the media device requesting the user to join the panel.

9. The method of claim 8 , further including receiving monitoring data from the instrumented application after the user has agreed to become a panelist.

10. The method of claim 8 , further including generating the unique identifier to be used by the media device.

11. The method of claim 10 , further including transmitting the unique identifier to the media device.

12. The method of claim 8 , wherein the application identifier is assigned to the instrumented application by at least one of the media provider or an application developer.

13. The method of claim 8 , wherein the assigning of the media device to into the first test cell is further based on a random value, wherein the random value is less than or equal to the skip rate and greater than or equal to zero.

14. The method of claim 8 , wherein the skip rate is based on a count of media devices in the master frame divided by a desired number of media devices for the panel.

15. An apparatus for creation of a panel, the apparatus comprising:

memory;

instructions; and

at least one processor to execute the instructions to cause the at least one processor to at least:

provide monitoring instructions to a media provider for creation of an instrumented application;

receive a unique identifier and an application identifier from a media device executing the instrumented application, the unique identifier and the application identifier received without collecting personally identifiable information;

create a master frame corresponding to media devices that have executed the instrumented application;

sort the master frame based on at least one of a date of installation of the application at the media device, an identifier associated with the application installed at the media device, or a number of instrumented applications installed on the media device;

assign the media device from the master frame into a first test cell based on a skip rate;

select a first recruitment interface associated with the first test cell, the first recruitment interface different from a second recruitment interface associated with a second test cell; and

instruct the instrumented application to, in response to the instrumented application being executed for a first time after a threshold period of time since an initial execution of the instrumented application has elapsed, display the first recruitment interface to a user associated with the media device requesting the user to join a panel.

16. The apparatus of claim 15 , wherein the processor is further to receive monitoring data from the instrumented application after the user has agreed to become a panelist.

17. The apparatus of claim 15 , wherein the processor is further to generate the unique identifier to be used by the media device.

18. The apparatus of claim 17 , wherein the processor is further to transmit the unique identifier to the media device.

19. The apparatus of claim 15 , wherein the application identifier is assigned to the instrumented application by at least one of the media provider or an application developer.

20. The apparatus of claim 15 , wherein the assigning of the media device to into the first test cell is further based on a random value, wherein the random value is less than or equal to the skip rate and greater than or equal to zero.
