Chapter 3 Working with a TI Calculator

117

MultiLab displays the fit formula:

5. Press

to display the curve fit on the graph screen

3. User Curve Fit

This option allows you to create your own curve fit formula.

1. Enter your equation to the

editor of your TI calculator

2. Run MultiLab and display the Select Analysis screen

3. Press

from the Select Analysis screen

4. Use the Up

and Down

keys to select a sensor, then press

5. Use the Up

and Down

keys to select a coefficient, then

press

6. Enter a new value for that coefficient, then press

MultiLab calculates the new fit equation and displays it together with
the analyzed data.
You can repeat the process in order to change the coefficient value or
to edit another coefficient.

4. Statistics

You can select a region of a data set and display statistics of the data range:

MINIMUM

–

The smallest value in the range

MAXIMUM

–

The largest value in the range

MEAN

–

The average of all the numbers in the range

STD. DEVIATION

–

The standard deviation

–

The number of data points in the range
