In meteorological statistics dispersion is one of the three components of the RMSE:
RMSE2 = MBE2 + sdbias2 + dispersion2
see for example Hou et al, 2001:

I've come across the interpretation of Dispersion as "The second highest value less the second lowest value." Is this a widely used measure? And if so, should it be added to the article? 210.55.130.65 21:01, 10 October 2006 (UTC)
- I've heard of similar things being used. The idea is simply the range, adjusted for the possibility of two outliers that should be ignored on the grounds that they are atypical. Michael Hardy 22:15, 10 October 2006 (UTC)
[edit] dispersion vs. precision
precision should be mentioned in the article. Jackzhp (talk) 20:43, 20 March 2008 (UTC)
