Activity pattern

Why r/askscience is classified as Event-driven

Oscylo reads the newest 52 weeks of posts, comments and unique contributors and gives each subreddit one of the patterns below. The figures behind the label are shown beside it.

Activity patternEvent-driven

Activity in r/askscience is concentrated in bursts, with less consistent timing across years. That pattern points to event-driven activity, though it stops short of naming a cause.

How the label is read

Concentration4.10×
2.5×

The busiest four weeks against the quietest, with the yearly trend taken out. At 2.5× or more the year counts as concentrated: Seasonal if the busy weeks came at the same time in earlier years, Event-driven if they did not, and Variable when there is too little history to tell.

Repeats on earlier years0.48
00.60

How closely this year's busy weeks match their timing in the three years before, on a scale from −1 to 1. At 0.60 or more the pattern counts as Seasonal.
