Methods and apparatus to create a panel of media device users

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.

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.
