RUNNING AVERAGE...
⌘5 Lets you click on a series of SINGLE points
while LabAnalyst keeps track of the
cumulative mean, standard deviation (SD), coefficient of variation (CV),
and standard error (SE). The program also shows the summed total of
all selected points, and the range (minimum and maximum values).
To select points for analysis, move the cursor to the point of interest
in the plot area and click once. Then move to the next point and repeat.
- You can eliminate a single mistake (the last point indicated
with a mouse click) with the delete key.
- To exit the routine, move the cursor to the RESULTS window and click
the mouse once (the cursor can be anywhere in the result window).
PAIRS DIFFERENCE... ⌘6 Calculates
the cumulative mean, SD, and SE of a series of PAIRS of points. You
select point pairs with mouse clicks (an example might be the peaks and
valleys of a ventilation trace). LabAnalyst measures the absolute difference between the points in the
pair. It also calculates the cumulative mean, SD, and SE of the time
intervals between points. As for RUNNING AVERAGE, the delete
key gets rid of the last pair of points selected.
NOTE: this operation DOES NOT highlight the results window title when
active, as can be seen in the example above.
