Question

Adam would like to buy a used car, and collected several data to evaluate the best model (such as age, price, weight, etc.) Thanks to a scatterplot, he established that the relation between age and weight is somewhat linear. He calculated that the correlation between age and weight is 0.512. Describe the association.

Answer 1

Answer: There is a strong association between age and weight.

Explanation:

The correlation coefficient (r) is used to describe the relationship between two variables.

`-1\leq r\leq1`

If r lies between -1 to -0.5 or 0.5 to 1, then there is strong association between them.

Here, Variables: Age and weight.

correlation coefficient = 0.512

That means, there is a strong association between age and weight.
