In the July 5 2019 versions of FX Draw and FX Stat, we have added the ability to add a normal distribution curve and a cumulative normal distribution curve for a data set.
The new graph types draw an idealized normal/normal cumulative curve for a selected dataset using the dataset’s calculated mean and standard deviation. They allow you to demonstrate how closely your data fits a normal distribution.
The cumulative normal distribution curve can be combined with the calculated cumulative frequency curve (as well as a cumulative histogram) to clearly demonstrate differences.
As part of this upgrade we have also added some smoothing to our cumulative frequency curves – particularly when produce from grouped data.
