qn8.
An educational psychologist believes that an individual’s reading speed (in words per
minute) and general comprehension abilities (scored out of 10) may be related to how
well they do on a timed exam. To study the relative importance of these variables and
the association between them, she runs a multiple regression. She produces the
following predictive model for exam score:
Exam Score = 7.78 + (0.10*Reading Speed) + (5.77*Comprehension)
What exam score would you expect students to achieve if they have a reading speed
of 300 w.p.m. and a comprehension score of 7?
a. 66.44
b. 16483
c. 78.17
d. 63.17
Qn9.
A private education company proposed an intervention programme to a school. The
programme is designed to lower anxiety in children. The programme would take up a
significant amount of the school’s budget. The education company provided the
results of a study showing that anxiety levels decreased in their intervention group
compared to a control group of children. The results of the t-test are t(6764) =
2.30, p =.02, d = .04. Given this result, what should the school do?
a. Instigate the intervention programme because it resulted in a statistically significant
decrease in anxiety.
b. Decline the programme because the results of the study were not statistically
significant.
c. Decline the programme because it had only a marginal impact on new word
acquisition.
d. Decline the programme because the sample size of the study was very small.
