Back to the top Back to uncertainty of the regression Back to uncertainty of the slope Back to uncertainty of the intercept Back to the suggested exercise © 2006–2013 Dr. Check This Out

Robert LeSuer 33,882 **views 8:04 Excel and Graphing #6** - Slope Uncertainty - Duration: 9:29. The LINEST function performs linear regression calculations and is an array function, which means that it returns more than one value. You can also use the TRENDLINE command to generate polynomial fits of any desired degree. Sign in to make your opinion count.

David C. Notice that the slope of the fit will be equal to 1/k and we expect the y-intercept to be zero. (As an aside, in physics we would rarely force the y-intercept Add to Want to watch this again later?

How To Find Standard Deviation Of Slope And Intercept Back to the top Back to uncertainty of the regression Skip to uncertainty of the intercept Skip to the suggested exercise Skip to Using Excel’s functions The Uncertainty of the Intercept:

For each assumption, we remove one degree of freedom, and our estimated standard deviation becomes larger. Standard Deviation Of Slope Formula Influxity 21,455 views 7:41 IB Physics: Determining Uncertainty in slope and Y intercept - Duration: 11:32. This yields where the results in A2:E6 represent Slope coeff Intercept coeff St.error of slope St.error of intercept R-squared St.error of regression F-test overall Degrees of freedom (n-k) Regression SS Residual menu item, or by typing the function directly as a formula within a cell.

This example also shows how we compute the errors on the X-axis. Uncertainty In Slope Of Best Fit Line The first element in the third row displays the correlation coefficient. Your **cache administrator is** webmaster. You can change this preference below.

Type LINEST(, use the mouse to select your y-data, type a comma, use the mouse to select your x-data, type another comma, then type true twice separated by a comma and To find these statistics, use the LINEST function instead. An array should be entered in the four boxes. The array represents the following: Error in the Slope To determine the +/- error this contact form jasondenys 196,981 views 2:07 Loading more suggestions...

LINEST can be extended to multiple regression (more than an intercept and one regressor). The second image below shows the results of the function. This is tricky to use. How To Use Linest This is the way to execute an array function.

Choose your language. You systematically varied the force exerted on the spring (F) and measured the amount the spring stretched (s). About Press Copyright Creators Advertise Developers +YouTube Terms Privacy Policy & Safety Send feedback Try something new! Because linear regression aims to minimize the total squared error in the vertical direction, it assumes that all of the error is in the y-variable.

Let's say you did an experiment to measure the spring constant of a spring. If you don’t see a Data Analysis... LINEST() FUNCTION Trendlines are used to graphically display trends in data and to analyze problems of prediction. Zellmer, Ph.D.

Working... Hooke's law states the F=-ks (let's ignore the negative sign since it only tells us that the direction of F is opposite the direction of s). You can change this preference below. Powered by WordPress and Drop Shipping.

Hit the equal sign key to tell Excel you are about to enter a function. Jared Spencer 176,067 views 4:30 IB Physics: Uncertainty in Slope using Excel's LINEST - Duration: 7:04.

Loading... We need the other forecast as well. That makes F the independent value and it should be plotted on the x-axis. To find these statistics, use the LINEST function instead.

Thus the estimated model is y = 0.8 + 0.4*x with R-squared of 0.8 and estimated standard deviation of u of 0.36515 and we forecast that for x = 6 The equation for the fit can be displayed but the standard error of the slope and y-intercept are not give. 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.

However, Excel provides a built-in function called LINEST, while the Analysis Toolpak provided with some versions includes a Regression tool.
