W-22 when the several variables are statistically controlled,
was tested using the filtered W-22 test as the criterion (y)
variable. Age (x^), sex (X2), I.Q. (x^), the Rush Hughes test
(x^), the Gray Oral (x^), and the Durrell test (x^) were the
control variables. The sums of squares, mean squares, and the
degrees of freedom for hypothesis three are presented in
Table VII.

With
1 and 225 degrees of freedom, F^ = 6.76. The F
obtained exceeded the F
(.05)
value. Therefore, the hypothesis
was rejected.
Hypothesis four, there will be no significant difference
in mean change between the exp'erimental and the control groups
as measured by the Gray Oral Reading Paragraphs when the
several variables are statistically controlled, was tested
using the Gray Oral test as the criterion (y) variable. Age (x^),
