Question

Which correlation coefficient would describe this situation: As variable A increases, variable B increases almost to the same degree?

a. -1
b. 0
c. 1
d. Between 0 and 1

Answer 1

The correlation coefficient that describes the situation where as variable A increases, variable B increases almost to the same degree is 1.

Step-by-step explanation:

The correlation coefficient that would describe the situation where as variable A increases, variable B increases almost to the same degree is c. 1. A correlation coefficient of 1 indicates a perfect positive correlation, which means that as one variable increases, the other variable increases exactly in proportion. In this case, as variable A increases, variable B increases in the same magnitude.

For example, if variable A represents hours of study per day and variable B represents test scores, a correlation coefficient of 1 would mean that as the hours of study increase, the test scores also increase proportionally.
