Dr. Smith has conducted a multiple regression analysis to determine if mathematics teachers' salaries in
Texas are predicted by the number of years of schooling that the teacher has completed, number of years
that the teacher has taught, and/or the Reading TAKS scores of their students. Dr. Smith finds structure
coefficients (rPREDICTOR with Yhat) equal to .5 for educ, .7 for years, and .25 for TAKS. What conclusions
can be drawn from this information?
The education variable accounted for twice the amount of variance in salary as did the Reading TAKS score.
The number of years that a teacher has taught holds a stronger relationship with salary than the Reading TAKS score
variable.
The years variable is the only one of value.
The reading TAKS score variable should not be considered to be at all predictive of salary.
All of the above.
