Answer:
100 or higher
Step-by-step 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.
