Imagine that you were told that the t -statistic for the slope coefficient of the regression line $\widehat { \text { TestScore } } = 698.9 - 2.28 \times S T R$ was 4.38 . What are the units of measurement for the t -statistic?
A) points of the test score
B) number of students per teacher
C) $\frac{\text { TestScore }}{S T R}$

D) standard deviations

Quizplus · Accepted Answer

The t-statistic is a dimensionless quantity that measures how many standard deviations the estimated coefficient is from zero.
