I have a voting system where projects are evaluated and given a score from 0 to 4.
I am calculating standard deviations for each but I now want to characterise standard deviations as something like 'low' or 'high' where:
'low' means a close grouping of scores (and thus concencus around the score)
'high' means a wider grouping of scores (and thus a lack of concencus around around the score)
'medium' might obviously be somewhere in the middle.
I think ultimately I want to be able to filter results something like all the project within 1 standard deviation of the mean, all projects within 2 standards deviations etc.
But how do I calculate 'within one standard deviation'?
Not a maths guys really so thanks for the help.
