Hi Charles, It's been a long time for me, but if I remember well you want either the first differences or the standard deviation.
function mean theNumbers return sum(theNumbers)/number of items of theNumbers end mean function firstDifferences theNumbers put mean(theNumbers) into myMean repeat for each line myLine in theNumbers add abs(myLine-myMean) to myCumulDiff end repeat return myCumulDiff/number of items of theNumbers end firstDifferences function standardDeviation put mean(theNumbers) into myMean repeat for each line myLine in theNumbers add( abs(myLine-myMean))^2 to myCumulDiff end repeat return sqrt(myCumulDiff/number of items of theNumbers) end standardDeviation on mouseUp put "-3.5,2.23" into myRow put mean(myRow) into myMean put firstDifferences(myRow) into myMeanDifferences put standardDeviation(myRow) into myStandardDeviation -- do with the variable whatever you want end mouseUp (Untested, please mind typos and other mistakes) -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering Homepage: http://economy-x-talk.com Twitter: http://twitter.com/xtalkprogrammer KvK: 50277553 How to receive a free Color Converter license http://qurl.tk/kv (read the conditions) On 12 dec 2010, at 21:20, Charles Szasz wrote: > I am computing an average of a series of numbers and then comparing each > number with the average, which yields a deviation.
