Question

Choose the best description for the relationship between the two sets of data in the scatter plot.

A scatter plot shows a line that falls from left to right. Data points are gathered loosely around this line.


Strong positive association


Strong negative association


Weak positive association


Weak negative association

Answer 1

Weak negative association

Explanation:

A scatter plot shows the relationship between two variables. The relationship between variables could be;

i) Strong positive association

ii) Strong negative association

iii) Weak positive association

iv) Weak negative association

If the line descends from left to right as stated in the question, it denotes a negative relationship.

The fact that data points are gathered loosely around this line means that the relationship is weak.

Hence the plot shows a weak negative association
