Following are the heights and weights of 10 students in a class. Draw a scatter diagram and indicate whether the correlation is positive or negative.

Height (in inches) : 72 60 63 66 70 75 58 78 72 62

Weight (in kg) : 65 54 55 61 60 54 50 63 65 50

Solution

Thus, there exists a very low degree of positive correlation between height and weight of students.
