== Normal_p1_p2( q1, q2, p1, p2 ) ==

This distribution function found in the [[:category:Distribution Variations library functions|Distribution Variations library]] defines a [[Normal distribution]] given any two percentile estimates.  «q1» and «q2» are the percentile estimates, and «p1» and «p2» specify which percentiles these are.  It must be that <math>q1<q2</math> and <math>p1<p2</math>.

For example, given that the 5% percentile is 5 and the 25% percentile is 8, the distribution is
:[[Normal_p1_p2]]( 5, 8, 5%, 25% ) &rarr; [[image:Normal_p1_p2_ex1.png]]

As with other distribution functions, you can also use this distribution in the function [[Random]].
