Format: S[ummary] [r[anks]] column [if condition]Outputs basic information about the data in a column - the total of the values in the column and the number of items, and the mean, mode, median, minimum, maximum, variance, standard deviation, standard error of the mean, skewness and kurtosis. Optionally a frequency and rank table of the values may also be produced.
Enter command - SUMMARY C15 Enter command - SUM C15 IF ROW<=50 Enter command - b ranks c19Example output:
A - C19 Column total=269.0 Number of items=100 Mean=2.690 Minimum=0.0 Maximum=7.0 Mode=0.0 Median=3.0 Variance=5.314 Standard deviation=2.305 Standard error of mean=0.231 No. Rank % Cum% Value 30 15.5 30.0 30.0 0.000000 8 34.5 8.0 38.0 1.000000 9 43.0 9.0 47.0 2.000000 15 55.0 15.0 62.0 3.000000 14 69.5 14.0 76.0 4.000000 7 80.0 7.0 83.0 5.000000 12 89.5 12.0 95.0 6.000000 5 98.0 5.0 100.0 7.000000Comments
Further detail about the syntax of the BASICS command is provided in the general section on command syntax.
If confidence limits have been requested (using the LIMITS command) then upper and lower confidence limits for the population mean will also be output.
If there is more than one mode then only the lowest will be output. If you suspect there may be more than one then you can either look at the frequency table or can issue the BASICS command again together with a condition which excludes the first mode found, e.g. if a mode of 1.5 is reported:
Enter command - b c19 if c19!=1.5Performing the SUMMARY command sets the values of the special variables XMEAN, XTOTAL and XNUMBER, in addition to the variables VV1, VV2, etc.
