Hi All,

I am working on an analysis of new delivery charges and and comparing existing pricing with a proposed new pricing.

I have 84k orders which I have calculated the average and standard deviation of difference in pricing between current/proposed pricing.

avg = =£1.03

stdDev = £40.25

80k of my order fall within 1 stdDev and in terms of value its £150k positive.

Is a stdDev of 40.25 good or bad? high or low? should it be closer to the avg in order to be more useful as info??

Thanks
