if the relationship between an explanatory variable x and a response y is positive and increasing but has some curvature, as shown by a trend line through the scatter, the correlation will be:

Respuesta :

As there is a positive correlation between the variables, the correlation will be larger than 0 and less than 1. The correct option is 0< correlation <1.

Given that,

Linear association is measured via correlation. A trend line drawn through the scatter will indicate a relationship between an explanatory variable X and a response Y that is positive and growing but has some curvature

To find : The correlation

From the provided information,

The two variables are positively related.

The correlation coefficient takes a value from -1 to 1.

Since, the correlation between the variables is positive, therefore, the correlation will be greater than 0.

Thus, the correct option is 0<correlation<1.
