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
