Error / Uncertainty in Excel
I'm a physics student trying to use excel for my experimental data.
After inputting my values and their uncertainties (the error of the values), I plot the values to find the slope and intercept but I can't find a way to include their errors. It's possible to include error bars, but they're just for show and don't actually do anything. Is there a way for excel to calculate the error / uncertainty of a slope and intercept? |

Error / Uncertainty in Excel
Jel -
The array-entered LINEST worksheet function provides standard errors of the regression coefficients. Or, for formatted output, use the Regression tool of the Analysis ToolPak (an add-in provided with Excel). - Mike http://www.MikeMiddleton.com "Jel" wrote in message ...
