    tests. From 2920 cases tested on all the six tests, tables of distribution of these mental indices were therefore made, and the percentile values for these indices determined. This procedure is necessary, because we are combining the results of six tests. A median percentile of 90 does not necessarily mean that the child is a ninety per cent child on all the tests combined. It will probably be higher, because a median of 90 indicates that the child is more than a ninety per cent child on three tests. A mental in- dex of 100 would mean that a child made 100 on four of the six tests and this would be very exceptional, as a matter of fact a performance that did not occur in any of the 2920 children under consideration. The table of median percentiles will be found in Part II where it can be used by the worker applying the tests.
