Question

dr. chen found that the as the number of hours of video game play increases, grades decrease. this result is an example of a ______ correlation.

d) curvilinear
c) zero
b) negative
a) positive

Explanation:

To determine the type of correlation, we analyze the relationship between video game hours (one variable) and grades (the other variable). A negative correlation occurs when one variable increases while the other decreases. Here, as video game hours increase, grades decrease, which fits the definition of a negative correlation. A positive correlation would be when both variables increase together, a zero correlation means no relationship, and a curvilinear correlation involves a non - linear relationship (not the case here).

Answer:

B) negative
