## 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.

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
