REPORTING COLOURED PROGRESSIVE MATRICES RESULTS

The most satisfactory method of interpreting the significance of person’s

total score is to consider it in terms of the percentage frequency with which a

similar score is found to occur amongst people of the same age. This has to

advantage over other methods that no a priori assumption is made that in

childhood the development of intellectual capacity is necessarily uniform or

distributed symmetrically. For practical purpose, it is conveinent to consider

certain percentages of the population and to group people’s scores accordingly.

In this way, it is possible to classify a person according to score obtained.

Grade:

1. Or “ intellectual superior”. If a score lies at or above the 95th percentile for

2. “de3finitely above the average in intellectual capacity”, if a score lies at or

3. “Intellectually average” if a score lies between the 25th and 75th

III + if a score is greater than the median or 50th percentile;

III - if a score is less than the median.

4. “Definitely below average in intellectual capacity” . if a score lies at or

below the 25th percentile;

IV - if a score lies at or below the 10th percentile.

5. “Intellectually average” if a score lies at or below the 5th percentile for the

age group.

The total score obtained, the consistency of an estimate and the grade

reached are conveniently summarised as in the following examples.
