As a school administrator, you have been asked to identify students who have scored at the 50th percentile or above on the wechsler intelligence scale for children—revised (wisc-r). this means that you must identify only those students whose scores on the test (the iq scores) are at least or higher.

100 or higher

Explanation:

The Wechsler Intelligence Scale for Children- Revised is a scale that tries to measure intelligence based on ten abilities. In addition, the IQ scores have a mean of 100 and deviation of 15. That being said, if we are considering the 50th percentile or above, then the kids selected for this test would have to have an IQ score of 100, being that 100 is the mean for the WISC-R.
