Question

you have noticed that there is a discrepancy in grades for children of single parents in your elementary school and decide to pilot test a tutoring program for these students. The outcome of the pilot study has shown a correlation of 0.30 between tutoring and increased performance for these students. Based on this, would you roll out the tutoring program on a larger scale? Why or why not?

Answer 1

No, it is not advisable to roll out the tutoring program on a larger scale because the correlation coefficient is only 0.30

We know that the correlation coefficient varies between -1 to +1 and a positive value shows that increase in one variable is also resulting in increase in other variable.

We can see that the 0.3 correlation coefficient is very weak correlation, which means that there is not a strong positive linear relationship between the tutoring and increased performance for these students. So, it is not beneficial to roll out the tutoring program on a larger scale.
