Statistics

Use the statistics tool to display statistics of a selected data set or a range of data.
The statistics include:
Average – The average of all the numbers in the range
StDev. – The standard deviation
Minimum – The smallest value in the range
Maximum – The largest value in the range
Sum – Adds all the numbers in the range
Area – The area between the graph and the x-axis in the range
Samples – The number of data points in the range
Rate – The recording rate
To display statistics:
1. Use the cursors to select the graph and the data range to which you want to
apply the statistics
2. Click Analysis on the menu bar, then click Statistics
MultiLab will open a statistics window and will display the results in it.

Most Common Analysis Functions

1.Linear fit

Click Linear Fit
and to display the line's equation.
Note: If you want the automatic curve fit equation to start at
the crop tool before applying the linear fit (see page 139).

2.Derivative

Click Derivative
the slope of the 3 consecutive points on the source graph.

3.Integral

Choose Integral from the Analysis menu to construct a graph in which each point is
the integral of all the preceding points on the source graph.
