I wish to construct a Normal Plot to visually test for normality of data. My data is:
And needs to be plotted to look something like this:
Whereby the data points are sorted from low to high and then plotted against the mid-point of their probability bins. So, in this case there are 10 data points so 10 bins with mid points of 5%, 15%, 25% etc. For this data, you would then see the lowest value (171) plotted at (171,5%), the next value (172) plotted at (172,15%) and so on.
Any ideas where I can find the answers?
