Call collection is driven largely by the availability schedules generated
during participant recruitment. This graph shows the nominal number of
available participants per 1 - hour timeslot for each day of the week.
The actual number of available participants is impacted by caller activity
(participants who have already made a call in the past 24 hours), non-participation
(participants who are deselected by failing to answer during when called),
and total platform activity (non-participation will result in deselection
at different rates depending on the number of attempted calls at a given
time). This graph also shows the number of successful calls per timeslot
This graph shows the cumulative number of calls collected since Nov. 12, 1999. The target number of calls to be collected is 1000. The black line represents the moving average of calls collected.
This graph shows a histogram of the Call In Progress and Skip Until Time entries into the database. These fields are updated each time a participant either calls into the platform or is called by the platform and actively accepts/rejects a call. A high, narrow peak correlates with a high level of activity on the platform.
The following graph shows the percentages of participants broken down by the number of calls made, received, and total.
This graph shows the breakdown of participants by age
