Marina Good Posted April 16, 2020 Share Posted April 16, 2020 I have tried numerous methods: Draw Curve from Data Table,inputting the statistical equation where it asks for the expression ([Column 1]+1.96*(Sqrt(([Column 1])*(1-[Column 1]))/100000)) based on the equation below), Line from Column Values, etc. The line does not appear on my plot even with the box checked for 'inlcuded in axis range'. Any thoughts For reference, I am working with logarithmically plotted frequencies, and have already been able to plot the curve I want in Excel using the following statistical expression: where p-hat is my frequency ([Column 1]), n is my population (100,000) and z is 1.96 for a 95% interval.

Shashank Gurnalkar Posted April 16, 2020 Share Posted April 16, 2020 One way that I tried is: Keep the [Column 1] on X-axis. Now use 'Draw curve...' from Lines & Curves and use the following expression in it: x + 1.96*Sqrt(x*(1-x)/1000)This may need further modification to make sense out of it.
