the picture below, the data points are shown by small, filled, black circles; each datum has error formula for calculating error in slope bars to indicate the uncertainty in each measurement. It appears that formula for finding error in slope current is measured to +/- 2.5 milliamps, and voltage to about +/- 0.1 volts. The hollow triangles uncertainty in y intercept represent points used to calculate slopes. Notice how I picked points near the ends of the lines to calculate the slopes! Draw the "best" line through all the points, https://www.youtube.com/watch?v=eV-RKGGrtA8 taking into account the error bars. Measure the slope of this line. Draw the "min" line -- the one with as small a slope as you think reasonable (taking into account error bars), while still doing a fair job of representing all the data. Measure the slope of this line. Draw the "max" line -- the one with http://spiff.rit.edu/classes/phys369/workshops/w2c/slope_uncert.html as large a slope as you think reasonable (taking into account error bars), while still doing a fair job of representing all the data. Measure the slope of this line. Calculate the uncertainty in the slope as one-half of the difference between max and min slopes. In the example above, I find 147 mA - 107 mA mA "best" slope = ------------------ = 7.27 ---- 10 V - 4.5 V V 145 mA - 115 mA mA "min" slope = ------------------ = 5.45 ---- 10.5 V - 5.0 V V 152 mA - 106 mA mA "max" slope = ------------------ = 9.20 ---- 10 V - 5.0 V V mA Uncertainty in slope is 0.5 * (9.20 - 5.45) = 1.875 ---- V There are at most two significant digits in the slope, based on the uncertainty. So, I would say the graph shows mA slope = 7.3 +/- 1.9 ---- V Last modified 7/31/2007 by MWR. Copyright © Michael Richmond. This work is licensed under a Creative Commons License.

How can I do this in MATLAB?I have tried to look into regression and regress but are getting very confused.Additional questions:What is the outputs of Regress? Does it gives the slope of the linear fit? And the 95% confidence intervals? I noticed that b not the same as the polyfit?Likewise, the polyfit does not give the same slope as regression. And Regression gives me matrix of result.. shouldn't slope just be one value. The inputs are just vectors of x,y data.Thanks 0 Comments Show all comments Tags regression Products MATLAB Related Content 2 Answers Jos (10584) (view profile) 4 questions 860 answers 262 accepted answers Reputation: 1,884 Vote0 Link Direct link to this answer: https://www.mathworks.com/matlabcentral/answers/53884#answer_65537 Answer by Jos (10584) Jos (10584) (view profile) 4 questions 860 answer
