## How To Calculate Standard Error Of Slope And Intercept

collect data, make a graph, find the slope of a function that fits that data and use formula for finding error in slope it for something. Well, what if need to find the uncertainty in the slope? How do you do that? There are a couple of ways you standard error of slope calculator can do this, neither are absolutely correct. However, if you write a formal lab report and you find the slope you MUST find the uncertainty in it. Here is some sample data. Suppose I measure the diameter and the circumference of several https://www.youtube.com/watch?v=eV-RKGGrtA8 roundish objects. Here is my data. So, I want to plot this and find a functional relationship between these two. With error bars, this is what it should look like: Now, I want to fit a linear function to this data. That should be ok, but what about the uncertainty? Method 1 - use uncertainty of data points I could get the ratio of C/d by just looking at each data point. This is not as good as the slope because the slope essentially uses all https://www2.southeastern.edu/Academics/Faculty/rallain/plab193/page1/page35/page36/page36.html the data points at once. In this method, I am going to find the slope as normal. In Excel, you could fit a trendline. Or, you could draw a best fit line. Either way, I would get something like this (I did this in Logger Pro): This gives a slope of 3.28 (compare to pi = 3.14). I could get a better slope if I required the fitting function to go through the origin (0,0), but I am not going to do that. In essence, the slope is: But, what if I just use one set of data points? Then I could use propagation of error as usual. This would give Where the delta - slope represents the uncertainty in the slope. For this method, just pick the data pair with the largest uncertainty (to be safe) - although hopefully, it won’t matter much. For this case, I will pick d= 0.06+/-0.002 m and C = 0.183 +/- 0.004 m. This would give an uncertainty in the slope of 0.2. I would write: (there are no units - they canceled) Method 2 The next method is better but a little tricky. Basically, if you draw a best fit line you could “wiggle” the line and still have it fit. This would give a minimum and a maximum slope. If you do the trendline in Excel, I am not sure how you would do this. If you do it by hand on graph paper, it would be easy. Here, I am going to manually fit two li

We focus on the equation for simple linear regression, which in slope is: ŷ = b0 + b1x where b0 is a constant, b1 is the slope (also called the regression coefficient), x is the value of the independent variable, and ŷ is the predicted value of the dependent variable. Estimation Requirements The approach described in this lesson is valid whenever the standard requirements for simple linear regression are met. The dependent variable Y has a error in slope linear relationship to the independent variable X. For each value of X, the probability distribution of Y has the same standard deviation σ. For any given value of X, The Y values are independent. The Y values are roughly normally distributed (i.e., symmetric and unimodal). A little skewness is ok if the sample size is large. Previously, we described how to verify that regression requirements are met. The Variability of the Slope Estimate To construct a confidence interval for the slope of the regression line, we need to know the standard error of the sampling distribution of the slope. Many statistical software packages and some graphing calculators provide the standard error of the slope as a regression analysis output. The table below shows hypothetical output for the following regression equation: y = 76 + 35x . Predictor Coef SE Coef T P Constant 76 30 2.53 0.01 X 35 20 1.75 0.04 In the output above, the standard error of the slope (shaded in gray) is equal to 20. In this example, the standard error is referred to as "SE Coeff". However, other software packages might use a diff

known or estimated uncertainties. The calculations may involve algebraic operations such as: Z = X + Y ; Z = X - Y ; Z = X x Y ; Z = X/Y ; Z = XY or mathematical functions of the type: Z = 1/X ; Z = ln(X) ; Z = log10(X) ; Z = 10X ; Z = eX ; Z = sqrt(X) . If uncertainties (dX, dY) are provided for the input quantities (X,Y), the program will perform the operation or function to calculate the answer (Z) and will also calculate the uncertainty in the answer (dZ). The program will assume the value has no uncertainty if an uncertainty is not provided. Operation: Position the cursor on the blank under "X", click the mouse, and type a value. Alternately, press the TAB key until the cursor appears in this blank, then type the number. In case of an error, use normal text-editing procedures. Enter values for X and dX, and possibly for Y and dY. (The TAB key moves the cursor through the blanks in the order: X, dX, Y, dY). Click on the button for the desired operation or function. The equation for the calculation appears in the central blank, and the values of Z and dZ appear in their respective blanks. There are buttons for transferring values from Z to a MEMory location, or to the blanks for X or Y; or from the MEMory to X or Y. top
