This article will cover how to check on the overall level of activity that the members of a group have shown over a period of time, and how the group’s average performance on BrainHQ exercises has changed over a period of time.
NOTE: This is the legacy version of our Group Portal. A legacy group can no longer be created. Additionally, current legacy groups will be migrated to the new group format soon. These articles are to support existing legacy groups until they have been migrated to the new version.
This information documents the activity and improvements that the members of a group are making. For example, you can use this information to let your supervisor or funder know about how many people have used BrainHQ over a certain period of time, and how much their cognitive function improved on average.
Start by going to the group portal page at portal.brainhq.com and logging into a group administrator account. Then click on the “Aggregate Data” tab.
Setting the Time Window
On the right, this page shows a date range, which controls the time window over which the group’s activity is calculated. By default, the time window starts in 2012 and goes through the current date, to show activity over all time. To change the time window, enter different start and end dates. For example, enter 01-01-2019 for a start date and 12-31-19 as an end date to review activity over the 2019 calendar year.
On the left, this page shows information about the overall activity of the group during the time window, including
- The number of new registrations (people added to the group)
- The number of active users (people who have completed at least one block of training)
- The total levels completed by all members of the group
- The total number of hours trained by all members of the group.
At the bottom, it shows a graph that indicates how the average cognitive performance of the group has changed over the time window.
The first row shows the average number of stars earned per active user. For example, showing “492 (5)” would mean that there were 5 active users, who earned an average of 492 stars each.
The second row shows the average number of levels completed per active user. For example, showing “633 (5)” would mean that there were 5 active users, who completed an average of 633 levels each.
The next six rows show the group’s performance for each BrainHQ cognitive domain (memory, navigation, people skills, intelligence, attention, brain speed). Each row shows the current average performance level as a percentile rank, and the number of users who trained in this domain. For example, showing “87th (4)” on the Attention row would mean that 4 users trained in the Attention domain in the time window, and that the 4 users had average percentile score in the Attention domain of 87. You can learn more about how BrainHQ calculates percentile scores here.
Each row shows additional information in graphical form:
- A small circle (showing the the average percentile score performance)
- A small triangle (showing the median percentile score performance)
- A solid colored horizontal bar (showing the performance range of the middle half of users)
- A thin colored line (showing the performance range from the lowest performing user to the highest performing user)
To the right of each graph, the average change in performance is also shown numerically. This is calculated as the average change across each member of the group. Every member who has a change score in the cognitive domain (i.e., who repeated at least one level) is included in the average, but if a member has not trained in the domain at all, they are not included in the average.
For example, if the group had 4 users who had trained in Attention over the time window, and their percentile scores in the Attention domain were like this:
- User 1: Baseline score 14, best score 82
- User 2: Baseline score 20, best score 93
- User 3: Baseline score 16, best score 76
- User 4: Baseline score 36, best score 82
The Attention row would show “87” (the rounded average of the groups best score) and “4” (the number of active users), and the graph would have a small circle at the +83 point, indicating that the average improvement was 83 percentile ranks.
