Select from the drop-down menu to correctly complete the statement.


The strength of association is:

Strong or weak?

Answer 1

The strength is strong because all the points are located in the same general place; the points are linear.

Answer 2

Strong

Explanation:

Given is a scatter plot for two variables are we are to find the strength of association between the two variables in the scatter plot

On analysis of the scatter plot, we find that whenever x increases, y decreses.

Hence there is a negative association between them

The points are very much near to the trend or regression line showing the there is a linear relationship between the two variables.

Whenever there is a linear relationship we find that there is constant slope which says that the rate of change of y varies as rate of change of x (negatively)

Hence there is a strong association.

The strength of association is:

Strong
