I don't believe the same principle applies to non-normal distributions but I will have to check that. 3. Or are both measurements effectively the same? Privacy Policy, The selection of sites taken in the mind if the triangle is formed well-shaped triangles. That is the value that defines where 50% of the values lie for a normal distribution. probable errors in base line measurements. This is the second volume of a proposed six volume series presenting a full opening repertoire for White, based on 1.d4. The Probable Error helps you determine what size your measurement increment should be. For a normal distribution, the % of results that fall between the average and 1 standard deviation above the average is about 34%.
