binning

1. 1
   verb

   Present participle and gerund of bin.

   He's binning the whole plan and starting again from scratch.

   Binning the readings into hourly intervals made the trend obvious.

   Note

   The verb doubles its final n before -ing, as run and sit do. After a form of be it is a participle (she was binning old letters); as a gerund it names the action, and in data work that gerund has hardened into the statistics technique. The throw-away meanings are informal and British; the data meaning carries no such label.

   Note

   A smoothing step that trades detail for stability: small measurement errors inside one interval vanish, but so do real differences. Bins can share one width or hold equal numbers of values, and the stand-in can be the bin's center, mean or median. A histogram draws on the same bins but counts the values rather than replacing them.
