Syntax The syntax for the SLOPE function in Microsoft Excel is: SLOPE( known_y_values, known_x_values ) Parameters or Arguments known_y_values The known y-values in data points used to calculate the slope. How can we improve it? That makes F the independent value and it should be plotted on the x-axis. The const and stats should be labeled true and true as shown below.

Example Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. Rating is available when the video has been rented. 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 Close Yeah, keep it Undo Close This video is unavailable.

Click OK In the table that is written into your worksheet, the slope is the number after "X Variable 1", and the error (standard deviation) in the slope is the number If known_y's and known_x's are empty or have a different number of data points, SLOPE returns the #N/A error value. If Data Analysis does not appear in the Tools menu: Select Add-Ins from the Tools menu Check "Analysis ToolPak" and click OK Data Analysis should now appear in the Tools menu It can be used as a worksheet function (WS) in Excel.

The first element in the third row displays the correlation coefficient. 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 first true tells LINEST not to force the y-intercept to be zero and the second true tells LINEST to return additional regression stats besides just the slope and y-intercept.

Such analysis is also called regression analysis. Trendline are useful but it does not give the error in the slope. The friendliest, high quality science and math community on the planet!
