An instructor hypothesizes an inverse relationship between using laptop computers in class and paying attention in class. Which of the following supports her research hypothesis?

A) r(30) = .38, p < .05
B) r(30) = .28, p > .05
C) r(30) = -.38, p < .05
D) r(30) = -.28, p > .05

Question

Thuto Morake · Accepted Answer

Final Answer : C, Explanation :  A negative correlation indicates an inverse relationship, and a correlation coefficient of -.38 means that as laptop use in class increases, paying attention in class decreases. The significance level of p < .05 means that this correlation is statistically significant and not likely due to chance.
