**MIDRANGE**(//dataset//)

{{blk2blue.jpg|blk2blue.jpg}}

| **MIDRANGE** | Returns the average of the highest and lowest value in a numeric set. |
| //dataset// | The label of a QUEUE with its first component field defined as a REAL. |

**MIDRANGE **computes the mean of the smallest and largest values in a data 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 midrange is (1 + 5) / 2 = 3.

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**

**MidrangeOfSet   REAL**
