Hey guys, I'm not really a math/science type so this is tough for me.
But I need to graph a set of price data znd the best fit line, and the -1 and -2 standard deviations. That should be 68% and 95% correct?
I've been using excel.
I can graph the data really easy as a scatterplot and add a linear fit. But then I how do I graph the standard deviations though?
Please someone help!
