In addition to letting you do equations, if you included functions that preform operations over the selected section (like sum, integrals, product, mode, average, stdev) then analyzing and iterating theory on data could be done much quicker.
Using these if I wanted to manually calculate variance (this is just an example, I know you could just square std.dev) the equation might look something like the following:
variance = (sum(x**2) - (sum(x)**2) / count()
And variance= would appear next to all of the other statistics (maybe bolded or indicated with an arrow to show it's custom)
Just a thought/feature that I think would add functionality and versatility to the program as a whole. Of course if really needed someone could just select and cut the data they wanted to and run their own coding scripts, but adding it directly would make things easier. Thanks for consideration!
