Question

When two variables have a negative correlation,
a. when the x-variable decreases, the y-variable decreases.
b. when the x-variable decreases, the y-variable increases.
c. when the x-variable increases, the y-variable increases.
d. more than one of the above is correct?

Answer 1

The correct answer is letter B, when x-variable decreases, the y-variable increases.

Because a negative correlation is a relationship, where one variable increases and the other one decreases.

Answer 2

Option (B) when the x-variable decreases, the y-variable increases is the correct answer.

What is negative correlation?

Correlation is the degree to which two or more quantities are linearly associated. Correlation in the opposite direction is called a negative correlation. A negative (inverse) correlation occurs when the correlation coefficient is less than 0.

For the given situation,

Two variables have a negative correlation.

From definition, two variables have a negative correlation when the x-variable decreases, the y-variable increases and the vice-versa.

Hence we can conclude that option (B) when the x-variable decreases, the y-variable increases is the correct answer.
