stats::median -- the median value of discrete data

Introduction

stats::median(..) returns the median of discrete data.

Call(s)

stats::median(x1, x2, ..)
stats::median([x1, x2, ..])
stats::median(s <, c>)

Parameters

x1, x2, .. - the statistical data: numerical real values.
s - a sample of domain type stats::sample.
c - an integer representing a column index of the sample s. This column provides the data x1, x2 etc.

Returns

an arithmetical expression. FAIL is returned, if the data are empty.

Details

Example 1

We calculate the median of a sequence of five values:

>> stats::median(3, 8, 5, 9/2, 11)
   
                                     5
      

Alternatively, the data may be passed as a list:

>> stats::median([3, 8, 5, 9/2, 11])
   
                                     5
      

Example 2

We create a sample:

>> stats::sample([[4, 7, 5], [3, 6, 17], [8, 2, 2]])
   
                                4  7   5
                                3  6  17
                                8  2   2
      

The median of the second column is 6:

>> stats::median(%, 2)
   
                                     6
      

Example 3

We create a sample consisting of one string column and one non-string column:

>> stats::sample([["1996", 1242], ["1997", 1353], ["1998", 1142]])
   
                              "1996"  1242
                              "1997"  1353
                              "1998"  1142
      

The median of the second column is calculated. In this case this column does not have to be specified, since it is the only non-string column in the sample:

>> stats::median(%)
   
                                   1242
