Group

What kind of events should our group hold?

Notice that there are 2 event type options. Orange groups with above average event frequency have events with below average attendance. Green groups with above average event attendance have below average event frequency.
Notice that the green groups with high attendance only have about 2 events semi-annually, so about an event every 3-month quarter.
Slide the event attendance slider to get a zoomed-in look at the green high attendance groups.
Slide the # of event hosted slider to get a zoomed in look at the orange high event frequency groups.

Not displayed on the graph: the typical attendance fee for paid events was between $0 and $20 with an average of just $10.

Highlight the groups that charge an attendance fee on the scatter plot to see how they are distributed.
Notice that the distribution of groups with free events filtered out looks quite similar to the distribution with all groups, so charging an entrance fee may have little impact on event attendance.
Look at the bottom right static graph. Notice that there is especially little difference in attendance from charging a fee for smaller groups. Niche groups may be better able to get away with charging a fee than general interest groups.
Compare the possible profits from high event attendance versus high event frequency with a quick calculation.
If your group could become the best at holding frequent events: $10 x 430 events x 10 attendees = $43,000 semi-annually.
If your group could become the best at holding high attendance events: $10 x 2 events x 250 attendees = $5,000 semi-annually.

Look at the bottom left static graph. Notice that event attendance only goes up by a couple of people as you go from 500 to 5,000 members, then as your member count continues to increase your attendance gains stop increasing at all.
