MOS 94l.i, cook6 .
Inrpection of the colum Gic’6 shown in Table 1 suggert that item6
above a readability level of 9th grade fail to predict the criterion.
The ric for 53 lteme with RI greater than 9th grade lo. .006, which ie
not significantly different from zero. The ?i, for the 44 items with
RI of 9 or lesr is .OSl. Thi6 Tic ir 6igdfiC6ntt,~ different from
�����
The difference between the two ‘Tic@6 is significant at the .Ol
level.
It is therefore concluded that the 53 item6 with RI greater than
9 contribute little to the volidity of this MOS Evaluation Teet.
The obtained validity of the test was .lO, Whatever validity the
test ha8 appear6 to cane primarily from itUiI6 with lower level6 of
readability.
MOS 111.6, Light Weapon6 Infant-n
Result6 for the LOO technical item6 are rhown at the left of Teblo
If, and reault6 for the 25 supervisory item6 are ahown on the right.
In the technical test,‘18 ittD6 with RI of 20 or higher have an
a&rage validity of 0.014. The validity of the te6t, therefore,-which
is .25, derive6 principally from item6 with a RI oelow 20. The ric
for it-6 with RI below 20 is .065, which is significantly different
from zero. The difference between the two riC’6 is significant at
the .05 level.
The supervieory tert can be divided st 14 itIm6 with RI up to 13,
and 11 items with RI of 14 or higher. The Fi,‘s are respectively .086
and .035. The former ie oignificantly different frcm zero and the
latter i6 not. The difference between them ie t!ot rtati6tically significant.
If the trend6 reflected in the rerults obtained to date are born
out by additional MS 6emple6, it is believed that a strong relationship
will have been demonstrated between the readability of teet items and
item-criterion correlations. Step6 can then be taken to write test
item6 at appropriate levels of readability. The result should be a
significant increase in the power of items to predict job proficiency
criteria.
