The statistics parameter has the attributes described in the following table.
Attribute
n
mean
stddev
min
max
If n equals zero (0), all other attributes are nil. If n equals 1, the stddev attribute is nil because
the standard deviation of a sample size of 1 is undefined.
The min and max entries each have the attributes defined in the following table.

When returned Description
Always The number of data points on which the statistics are based
When n > 0
The average of all readings added to the buffer
When n > 1
The standard deviation of all readings (samples) added to the buffer
When n > 0
A table containing data about the minimum reading value added to
the buffer
When n > 0
A table containing data about the maximum reading value added to
the buffer
Description
String indicating the function that was measured for the reading (current,
voltage, ohms, or watts)
The full-scale range value for the measurement range used when the
measurement was made
The reading value
String indicating the source function at the time of the measurement
(current or voltage)
String indicating the state of the source (off or on)
Full-scale range value for the source range used when the measurement
was made
If bufferVar.collectsourcevalues is enabled, the sourced value in
effect at the time of the reading
Status value for the reading; the status value is a floating-point number that
encodes the status value into a floating-point value
If bufferVar.collecttimestamps is enabled, the timestamp, in
seconds, between when the reading was acquired and when the first
reading in the buffer was acquired; adding this value to the base timestamp
produces the actual time the measurement was acquired
