WinDaq Waveform Browser's Statistics Function

Function	Description
CHANNEL #/UNITS	Selected channel CH #/ engineering units
# OF POINTS	n, including all uncompressed data points in and between the time marker and cursor
MEAN	SUM/n, average of data points from START TBF through END TBF
STD DEVIATION	Sqrt(VARIANCE)
MINIMUM	Lowest data value
MEDIAN	Middle value in array sorted by value, or average of two if n is even
MAXIMUM	Highest data value
RMS	Sqrt((SUM OF SQUARES)/n), or root mean square
SUM	Sum of n data values on channel CH
SUM OF SQUARES	Sum of n (data value)*(data value) on channel CH
VARIANCE	SUM OF SQUARES) - SUM*SUM)/(n-1)
SKEWNESS	3*(MEAN - MEDIAN)/(STD DEVIATION)
SLOPE	(sum of n (data value)(# of half sample intervals from center))6/(n(n-1)(n+1)*(sample interval)) = linear regression slope, where center = ((START TBF) - (END TBF))/2 is between samples if n is even
AREA	SUM*(sample interval = time interval between samples on channel CH)
START TBF	Time at first point in leftmost (possibly compressed) point
END TBF	Time at last point in rightmost (possibly compressed) point
FILE	Name of data file containing this data
COMMENT	Comment typed by user
