Question
The following graph shows ______________ type of association.
- Positive
- Negative
- No association
- All of the above
Hint:
If the points on a scatter plot move downwards from left to right, the relationship represented by the given scatter diagram between the 2 variables (represented on x-axis and y-axis) is a negative relationship.
The correct answer is: Negative
GIVEN-
Scatter diagram representing relationship between 'Amount of time spent training' and 'Time taken to run a 100 m'.
TO FIND-
Nature of association shown by the given graph.
SOLUTION-
From the given graph, we observe that the scatter points move downwards from left to right. i.e. as the drivers' age increases, the distance from which a traffic sign is legible (i.e. visibility) decreases.
Hence, the given graph shows a negative association between drivers' age and sign legibility distance.
FINAL ANSWER-
Option 'b' i.e. 'Negative' is the correct answer to the given question.
