How to Find Slope on Logger Pro

Y Click on the Tutorials folder and click on Open. In the case of this particular Logger Pro sample analysis you would want to determine the uncertainties in your slope and y-intercept.

Logger Pro And Graphing 3 Linearization Slope Uncertainty Youtube

The program should automatically detect the interface and the motion detector.

. Open the Applications folder and then open Logger Pro folder and double-click the Logger Pro icon. Find the stationary points on the curve y x 3 - 27x and determine the nature of the points. On the right enter slope and intercept values that are close to but not exactly the best fit values.

A new line appears on the graph with a new. Opening the file in Logger Pro 1. This should be This should be y A t 2 B t C 3.

Enter the X axisvariable name into Name and Short Nameuse the same variable in each field ie. For this method just pick the data pair with the largest uncertainty to be safe - although hopefully it wont matter much. Select the best fit button shown below.

In the Logger Pro Analyze menu and choose the most appropriate general equation. The students use their EOL from the x vs. This can be done by using the Model function under the Analyze menu button.

The numerical derivative is the weighted average of the slope of n points around each point. Click Page - Auto Arrange. In Logger Pro go to the File menu and select Open.

Also appears with slope and intercept values. 2standard deviation of slope SQRT n σy standard deviation of y-intercept SQRT σy2 xi2 where. This PDF document ensures that superscipts and subscripts are not lost.

For this case I will pick d 006-0002 m and C 0183 - 0004 m. Click Insert - Graph in the upper menu bar. T2 graph to have Logger Pro plot a position-time graph that has more data than.

Open Logger Pro 2. You can fit a line either to the whole graph or to a region of interest. Write in the correct variable name INCLUDING A SHORT NAME AND INCLUDING UNITS.

A perfect correlation with positive slope is shown by a 1 correlation while a negative slope is shown by a -1 correlation. Find the Logger Proicon in the dock and click to open it. A column of real numbers.

On the toolbar select AnalyzeModel. Double Click on the X variable in the Data Set the Column Options window will appear. N number of data pairs 2 n xi - xi2 sx standard deviation of x data sy standard deviation of y data 1 2 σy --------------- yi- B - M xi2 n-2.

Where the delta - slope represents the uncertainty in the slope. A column of real numbers X. In the new window that appears select mxb Linear on the left.

To get max and min lines on the graph. This would give an uncertainty in the slope of 02. If you dont supply an X column the program will find one.

Find the link to the movie and the cmbl file given in the homework problem and download them to your desktop. Y mx b 1 Where y is the y-axis x is the x-axis m is the slope and b is the y-intercept where the line crosses the y-axis. Do the same for your Y column for your dependent variable.

If you consider your extreme end points the error bars indicate that the slope of your line will have a maximum and minimum possible value. Logger Pro Best-Fit Instructions with Uncertainty 1. At stationary points dydx 0 dydx 3x 2 - 27 If this is equal to zero 3x 2 - 27 0 Hence x 2 - 9 0 dividing by 3 So x 3 x - 3 0 So x 3 or -3 How To Get Second Derivative Graph For Logger Pro Mac d 2 ydx 2 6x.

Using the slope from the logger pro graph of tan 0 vs. Y Determine which Temperature Probe you are using. I which you plotted in the lab magnetic fields calculate the value of Bearth in Gauss recall that 1Gauss 10-4 T assuming that the radius of the ring is R 20 cm and the number of turns is N 5.

The equations used are linked below. Enter your data into the X column. Temperature Tutorial 8 Logger Pro The Logger Pro screen contains from top to bottom the following major elements.

You can check for this by clicking on the icon located in the upper left-hand corner of the Logger Pro window. A correlation coefficient of 0 means that there is no linear relationship. G m mL 2 Rearranging 2 gives us the meaning of the slope.

At the top of the screen click File then Open 2. How to use Logger Pro in high school especially International Baccalaureate sciences to make good graphs for lab reportsIn this video we look at another. This button is part.

Variables are linearly related. Logger Pro Experiments Tutorials Open the file called 12 Video Analysiscmbl and follow the instructions. Rename the X column to your independent variable.

Drag the mouse across the desired. Logger Pro calculates the best fit line on graphs by using linear regression by the method of least squares. Highlight the data points on the graph you are interested in.

Open the following folders. The way we generate the graphs is by a little Logger Pro magic. The RMSE value is another way at looking at how.

Yesterday we defined instantaneous velocity as the slope of a tangent line to a non-linear position- time graph at a instant clock reading and a position. The menu bar a toolbar containing the Collect button a graph window a data window and a status bar. According to Table 1 you will graph grams as y and milliliters as x so that equation 1 above becomes.

This instructional video shows how to find the slope of a graph and the RMSE using Logger Lite on a netbook. To find the slope of a graph. A dialog box will open.
