You read that "the correlation between spending on schools (dollars per pupil) and median score on student achievement tests is r = 0.08." This means that
A) school districts that spend a lot have higher scores than low-spending districts, and this effect is quite strong.
B) school districts that spend a lot have lower scores than low-spending districts, and the effect is quite strong.
C) school districts that spend a lot have somewhat higher scores than low-spending districts, but the effect is weak.
D) school districts that spend a lot have somewhat lower scores than low-spending districts, but the effect is weak.
