TY_Track Posted February 11, 2017 Report Share Posted February 11, 2017 Hello! I'm doing my Math IA and I don't know how to present my standard deviation calculations in the report. I know I have to show an example of my calculations, but I'm not sure how to do this. I have 100 data points, and I'm not keen on calculating it all by hand. What would be the best way to do this? Any advice would be very appreciated! /Polly Reply Link to post Share on other sites More sharing options...
kw0573 Posted February 11, 2017 Report Share Posted February 11, 2017 Assuming you have a way to show the mean. Then for one data point, you show (x - mean)^2 And you show adding them up and plugging into formula. Or you can also show two data points and keep a running tally of the sum of squares.
