1. This data set IQ.sav is a real data set that was used to assess the bias in student outcomes
from the expectations of teachers. Students were randomly assigned to two conditions. In
the control condition, the teachers were given no information about the students. In the
treatment condition, the teachers were told to expect “unusual
academic development.” Students were tested 3 times throughout the school year using
the same IQ test. There are 5 variables in the data set: Grade (of the student), Condition
(“bloomer” or “control”), and the IQ tests at the 3 times points: IQPre, IQ4, IQ8 (posttest).
a. Write down the full and restricted models to test whether or not the means of the
“bloom” and “control” were the same in the post-test data. Include the df for each
model.
The full model is:
IQ8 = β0 + β1 ∗ condition + 𝜖
The degree of freedom = total observation – (1+1) =310-2=308
Restricted Model is:
IQ8 = β0 + 𝜖
The degree of freedom = total observation – 1 = 310 − 1 = 309

b. Write down the full and restricted models to test whether or not the means of the
grades were the same in the post-test data. Inclu...
