**RANGEOFSET(****//dataset//****)**

{{blk2blue.jpg|blk2blue.jpg}}

| RANGEOFSET | Returns the difference between the largest and smallest values in a numeric set. |
| //dataset// | The label of a QUEUE with its first component field defined as a REAL. |

RANGEOFSET computes the difference between the largest and smallest values in a numeric set. The function operates on the numeric set defined by all the entries in the first component of the designated QUEUE (//dataset//).

For example, given the data set: [1,2,3,4,5], the range is (5 - 1) = 4.

The passed data set does not have to be sorted. The function copies the passed set. The passed data set is unchanged.

**Return DataType:** REAL

**Example:**

StatSetX   QUEUE,PRE()

X        REAL

END

RangeOfSetX   REAL
