median

Computes the median of the values in this iterable.

The median is the middle value when the data is sorted. For an even number of elements, it is the average of the two middle values. Unlike the mean, the median is robust to outliers.

Example:

listOf(3.0, 1.0, 2.0).median()      // 2.0
listOf(1.0, 2.0, 3.0, 4.0).median() // 2.5

Computes the median of the values in this array.

The median is the middle value when the data is sorted. For an even number of elements, it is the average of the two middle values. Uses introselect (O(n) expected time) instead of a full sort for efficiency.

Example:

doubleArrayOf(3.0, 1.0, 2.0).median()      // 2.0
doubleArrayOf(1.0, 2.0, 3.0, 4.0).median() // 2.5

Computes the median of the values in this sequence.

The sequence is materialized internally. See DoubleArray.median for details.

Computes the median of the Long values.

Values are converted to Double internally. Long values whose absolute value exceeds 2^53 (9,007,199,254,740,992) may lose precision in the least-significant digits.

Example:

listOf(1L, 2L, 3L, 4L).median() // 2.5

Computes the median of the Int values.

Values are converted to Double internally. The conversion is exact for all Int values.

Example:

listOf(1, 2, 3, 4).median() // 2.5
