What is the best description for this scatter plot?
Homework Answers
From the given Scatterplot,
We can say that,
As there increasing or decreasing is not observed, The correlation coefficient between physical health and mental health is approximately 0(zero).
i.e., There is no correlation between this two variables as points are randomly scattered without showing any type of pattern.
Thank you.
