When a scatter plot is created for 3rd Period, the correlation
value is r=0.84/r=0.71/r=0.96/r=0.55
which means the data is weakly positively correlated/strongly positively correlated/moderately positively correlated/strongly positively correlated

If a rising 8th-grader shows up to this class with a beginning
of year scale score of 490, the predicted end of year
diagnostic score would be around 521/500/507/514/511.
