Some event types include numerical values, such as scores, virtual currency counts, etc. and Sum and mean calculations can be applied to them. Events without numerical values attached won’t show a sum or mean, but you can get their count. We are also in the process of introducing an aggregation called ‘Histogram’, which is currently limited only to looking at session length distribution. You can set the aggregation according to your preferences.
Mean - The average number of times an event was sent by a player, For instance, the mean of ‘New Users’ for time period of a week would be the average number of users for from the 7 days.
Count - The number of times an event was sent. For instance, the number of ‘New Users’ over a period of time.
Sum - Is the combined total of an event. For instance, you can look at the sum of transactions (revenue) which will be the total revenue generated by transactions over a period of time.
Histogram - An accurate representation on the distribution of a metric. For instance, number of sessions.
