11.3 PRINTING SUMMARY STATISTICS
The =. at command is used to generate summary statistics from selected data in a file. If the data file
has been generated by the = TEIF or MOMHI TOE programs, the program will summarize readings for an
individual trace. If the data file has been generated by the Ll: program, the program will request the
group number and the channel channel number to be summarized. The results may be presented one at a
time in the display, or printed on the current FE IMTER 15 device.
The statistics calculated from the data are:
e Number of data points (records)
e¢ Minimum and maximum values
e Sum of values
e Mean and standard deviation of values
e¢ Variance
e Standard error of the mean
The standard deviation, variance, and standard error of the mean are calculated using n-1I as the degrees
of freedom - that is, sample statistics are calculated.
Refer to the HP-71 Reference Manual for
additional information on how the statistics are calculated.
