Description

• 

Important: The stats package has been deprecated. Use the superseding package Statistics instead.

• 

The function range of the subpackage stats[describe, ...] finds the minimum and the maximum value of the observations in data.

• 

The boundaries of the classes are used for grouped data. Missing data are ignored.

• 

The range is a measure of dispersion of the data. For more information about such measures, refer to the standard deviation.

• 

The range is useful in finding appropriate boundaries for tallying data (see transform[tallyinto] - note that the upper boundary of classes are exclusive for tallyinto), and for histograms (see statplots[histogram]). One disadvantage of using the range as a dispersion measure is that it is strongly dependent on the extreme values in the data.

• 

The data must be numeric.

• 

The command with(stats[describe],range) allows the use of the abbreviated form of this command.

Examples

withstats:

The minimum and maximum of the numbers 5, 6, 1, 9 are 1 and 9 respectively:

describe[range]5,6,1,9

1..9

(1)

For grouped data, it gives the minimal and maximal edge of the classes.

describe[range]Weight1..2,6,Weight3..7,8

1..7
