Click the show uncertainty box, a check mark should appear. Tip: To view the uncertainties associated with the liner fit parameters, left click anywhere on the linear fit box and select "Linear Fit Options.". Now, determine the acceleration and its uncertainty using the 'Linear Fit' option in Logger Pro. Use Logger Pro to create the graph including error bars. \hline\( t(\mathbf \) are the same for all experimental points. This can happen since the min and max are determined using only two points, and not all the data.The results of measurements of speed, \( v \), of a particle versus time, \( t \), for constant acceleration motion, are given in the table below: Note that if the whole set of points is used for determining the best slope, and the above method is used to determine the min and max slopes, it is possible to have the best slope not be between the min and max slopes. The slope of this line is your maximum slope. Using the draggable line handles, move the line so that it runs from the bottom of the error bar on the left-most point to the top of the error bar on the right-most. The slopes (and the slope uncertainty) are the same. Add another Model and set it to use line drag. Below is a Logger Pro file showing two linear fits of almost the same data the data sets are just horizontally offset by 100 units.The slope of this line is your minimum slope.

Using the draggable line handles, move the line so that it runs from the top of the error bar on the left-most point to the bottom of the error bar on the right-most. If the X axis is scaled from zero, then the right handle will control the slope while leaving the Y-intercept alone. The center handle adjusts the Y-intercept, the outer two handles can be used to rotate the line about the far edge. The movable linear fit can now be adjusted by dragging one of the three handles on the line.
