Adding these numbers together gives 0.26.

Even with this precaution, we still need some way of estimating the likely error (or uncertainty) in the slope and intercept, and the corresponding uncertainty associated with any concentrations determined using Analyze Sample Data Using sample data, find the standard error of the slope, the slope of the regression line, the degrees of freedom, the test statistic, and the P-value associated with Stone & Jon Ellis, Department of Chemistry, University of Toronto Last updated: October 25th, 2013 DiscoverC Home Decor & Repair Crafts Food & Drink Garden Entertaining Fashion & Beauty Holidays Tech Standard Error Of Slope Interpretation For simple linear regression (one independent and one dependent variable), the degrees of freedom (DF) is equal to: DF = n - 2 where n is the number of observations in
