Answer:

The given correlation is a strong positive correlation, and it is not likely causal.

We have given that,

The correlation coefficient relating the two variables is 0.74.

What is the correlation coefficient?

The correlation coefficient value is used to determine the strength of the linear relationship between two variables. The value ranges from - 1 to +1.

The correlation coefficient value is used to determine the strength of the linear relationship between two variables. The value ranges from - 1 to +1.

with negative values depicting a negative relationship and positive values showing a positive relationship.

The value of 0 implies that no relationship exists.

The closer the correlation coefficient value is to +1 or - 1, the greater the strength of the relationship between them.

Also, correlation does not mean causation.

Hence, a correlation coefficient of 0.74 depicts a strong positive relationship.

However, it doesn't imply causation.

We have the given correlation coefficient relating the two variables is 0.74 and it is near +1

Therefore, the given correlation is a strong positive correlation, and it is not likely causal.
