Smoothing Data

The Smooth command (Data menu) averages irregular data to make a graph of the data appear much smoother. A running type of average (algorithm) is used to smooth selected columns of data. The results are placed in the next available empty column, or in any other column you specify in the Smooth dialog. Smoothing functions include 3- and 5-channel binomials, and 3-, 5-, 7-, and 9-point moving averages. 

Step 1
Choose the Smooth command from the Data menu.

Step 2
For the Variable (x) option, select the column that contains the data you want to smooth.

Step 3
Next to the Put Result In, enter the name of the destination column for the smoothed data. If you want the result in a new column, enter a name for the new column in this space.

Step 4
Click OK to smooth the data.
