It now becomes necessary to examine more closely just what are the
limits of step 3. It is evident from what has been said above that 3.69
is the middle step 3 and that step 3 extends downward from 3.69 halfway
to 2.60, and upward from 3.69 halfway to 4.74. The table given below
shows the range and the length of each step in the Hillegas Scale for
English Composition.
THE HILLEGAS SCALE FOR ENGLISH COMPOSITION
======================================================
STEP No.|VALUE or SAMPLE|RANGE OF STEP |LENGTH OF STEP
--------+---------------+--------------+--------------
0. . . .| 0 | 0- .91[32] | .91
1. . . .| 1.83 | .92-2.21 | 1.30
2. . . .| 2.60 |2.22-3.14 | .93
3. . . .| 3.69 |3.15-4.21 | 1.07
4. . . .| 4.74 |4.22-5.29 | 1.08
5. . . .| 5.85 |5.30-6.30 | 1.00
6. . . .| 6.75 |6.30-7.23 | .93
7. . . .| 7.72 |7.24-8.05 | .81
8. . . .| 8.38 |8.05-8.87 | .82
9. . . .| 9.37 |8.88- |
======================================================
From the above table we find that step 3 has a length of 1.07 units. If
we count out 35 of the 39 papers, or, in other words, if we pass upward
into the step .90 of the total distance (1.07 units), we shall arrive at
a point .96 units (.90 × 1.07 = .96) above the lower limit of step 3,
which we find from the table is 3.15. Adding .96 to 3.15 gives 4.11 as
the median point of this eighth grade distribution.
The median and the percentiles of any distribution of scores on the
Hillegas scale may be determined in a manner similar to that illustrated
above, if the scores are assigned to the individual papers according to
the directions outlined above.
