Height and weight are positively correlated. This means that:
A
Height and weight have a perfect negative correlation.
B
As height increases, weight tends to increase as well.
C
There is no relationship between height and weight.
D
As height increases, weight tends to decrease.
Verified step by step guidance1
Understand the meaning of correlation: Correlation measures the strength and direction of a linear relationship between two variables.
Recall that a positive correlation means that as one variable increases, the other variable tends to increase as well.
Recognize that a perfect negative correlation would mean that as one variable increases, the other decreases perfectly, which is not the case here.
Identify that 'Height and weight are positively correlated' implies that taller individuals tend to weigh more on average.
Conclude that the correct interpretation is: As height increases, weight tends to increase as well.
