I'm looking for a nice simple program that will let me plot the points
for a scattergram, give it a best fit line and then read an unknown. I
would love to hear some suggestions.
All I need it to do is accept the standards for the X axis and Y axis
and then give me the reading when I give it an unknown reading off of
one of the axis.
The program can be either PC or Mac based, or even on the web.
TIA for any suggestions.
