Question 3: What factors predict final reading
scores? Three independent variables were said to predict
the dependent variable (reading at time two). These were
subject to a stepwise linear regression – spelling at time two
(step 1), sounds (step 2) and visual search (step 3). Sounds
and visual search did not significantly contribute to the
amount of variance explained in the independent variable.
For the model composing of spelling at time two, R2 = 0.43.
The beta value, standard error and significance value for
spelling at time two are shown in the following (Table 2).
