To find:If the graph shown below shows any co-relation.
Answer to Problem 69SR
The graph below shows a positive co-relation. Though, the points are scattered still a positive co-relation can be observed.
Explanation of Solution
Given:
The given graph is
In the graph, the test scores are plotted against the study time. It can be observed from the graph that the test scores are higher when the study time in minutes increases. The less study time can be directly related to less test scores.
From the observation, though the test scores are scattered, still a positive co-relation can be established between the test scores and the study time.
