## Uncertainty In Slope Of Best Fit Line

Linest() function in Excel gives the error (or uncertainty) how to find standard deviation of slope and intercept for data in the lab. It calculates the statistics for a line

## Formula For Finding Error In Slope

by using the "least squares" method to calculate a straight line that best fits your data, and returns an array that https://www.youtube.com/watch?v=eV-RKGGrtA8 describes the line. Because this function returns an array of values, it must be entered as an array formula. An array should be entered in the four boxes. The array represents the following: http://web.alfredstate.edu/quagliato/linest/linest.htm Error in the Slope To determine the +/- error in the slope and the y-intercept, an array must be created. Go back to the original spreadsheet and highlight 4 empty boxes as shown below. Click the mouse in the formula box and enter the LINEST function. =LINEST(B2:B12,A2:A12,true,true) The B2:B12 interval represent the known y values and the A:2:A12 interval represent the x values. The LINEST function will evaluate the errors in the slope and y-intercept for a data set. The const and stats should be labeled true and true as shown below. IMPORTANT: To enter an array, hold down the Ctrl and Shift keys at the same time and then press Enter.

treated statistically in terms of the mean and standard deviation. The same phenomenon applies to each measurement taken in the course of constructing a calibration curve, causing a variation in the slope and intercept of the http://www.chem.utoronto.ca/coursenotes/analsci/stats/ErrRegr.html calculated regression line. This can be reduced - though never completely eliminated - by http://www.real-statistics.com/regression/hypothesis-testing-significance-regression-line-slope/ making replicate measurements for each standard. Multiple calibrations with single values compared to the mean of all three trials. Note how all the regression lines pass close to the centroid of the data. Even with this precaution, we still need some way of estimating the likely error (or uncertainty) in the slope and intercept, and the in slope corresponding uncertainty associated with any concentrations determined using the regression line as a calibration function.

The uncertainty in the regression is therefore calculated in terms of these residuals. Technically, this is the standard error of the regression, sy/x: Note that there are (n − 2) degrees of freedom in calculating sy/x. This is because we are making two assumptions in this equation: a) that the sample population is representative of the entire population, and b) that the values are representative of the true y-values. For each assumption, we remove one degree of freed

Observation:Â By Theorem 1 of One Sample Hypothesis Testing for Correlation, under certain conditions, the test statistic t has the property But by Property 1 of Method of Least Squares and by Definition 3 of Regression Analysis and Property 4 of Regression Analysis Putting these elements together we get that where Since by the population version of Property 4Â ofÂ Regression Analysis it follows that Ď = 0 if and only if Î˛ = 0. Thus Theorem 1 of One Sample Hypothesis Testing for CorrelationÂ can be transformed into the following test of the
