The correlation coefficient's value indicates how strongly two variables are related. Correlation coefficient values vary from -1 to +1. No correlation between two variables is shown by a value of 0, a perfect positive relationship between two variables is indicated by a value of 1, and a perfect negative relationship between two variables is indicated by a value of 0. The correlation between the two variables is greater the higher the correlation coefficient is.
Scatterplot with r=0.03:
In comparison to the other two scatterplots, scatterplot 2's data are more dispersed. In other words, no pattern has been noticed. On the other hand, scatterplot 3 and scatterplot 1 are roughly linear.
As a result, among the supplied values, the scatterplot 2 is anticipated to have the lowest correlation coefficient value and the scatterplot 1 to possess the highest correlation coefficient value. The right response is that scatterplot 2 (which corresponds to the data set with r=0.03).
