In immediate need of help with error analysis

  1. Sep 23, 2010 #1
    1. The problem statement, all variables and given/known data

    I have used excel to make a linearized fit of data - x and y variables - with no problem. But I must solve for a value that can only be extracted from my slope, also not a problem. My problem is I don't know how to calculate the uncertainty for my slope, based on the fit. I can do individual standard deviations for each column, but I don't know what to do with the slope.

    I would appreciate any help, as this is the only thing keeping me from finishing this lab report.

    Thanks!
