Hi! I used the two suggestions on this thread:
http://www.mrexcel.com/forum/showthread.php?t=19785
to make a graph with the frequency distribution (histogram) and normal distribution curve.
However, I have a question about how I can make sure that the values on the Y axes are correct such that the curve is fitting the histogram correctly. That is, I can change the max in the Y axis to make the curve go above or under various parts of the historgram, so how do I know what the correct values are such that they historgram and curve are exactly where they should be in relation to each other? This is more of an issue now that I'm trying to fit two different data sets onto the same graph (pre-intervention vs. post-intervention) and the curves are different heights, and the frequency distributions have different max values.
Thanks!
Carole
