Question

Transcribed Image Text:The following equation was estimated by OLS:
Unipa = 1.392 - 0.0135 psperc + 0..00148 sat
n = 4,137, R2 = 0.273
Where unipa is measured on a four-point scale, psperc is the percentile in the post-
sixteen class (defined so that, for example, psperc =5 means the top 5% of the
class), and sat is the combined maths and verbal scores on the student
achievement test.

Transcribed Image Text:Holding psperc fixed, what difference in SAT scores leads to a predicted unipa
difference of .50, or one-half of a grade point? Comment on your answer.
