Correlation coefficient is a value that ranges from -1 to 1, which is used to describe the relation between two variables.
From the scatter plot that is shown in the graph above, we can observe that the set of data represented are not clustered far apart from each other along the line of best fit. This suggest a correlation coefficient of lesser value close to zero which shows weaker correlation between variables. Also, we can observe that There's a downward slope signifying a negative relationship. As one variable increases, the other variable decreases.
Therefore the correlation coefficient that will match the set of data shown is -0.21.
