Use a graphing calculator to find the value of the correlation coefficient r and determine if there is a strong correlation amon
Natali [406]

The value of the correlation is -0.0721 and it is a weak negative correlation

<h3>How to determine the correlation coefficient?</h3>

The points are given as:

(12, 28), (15, 50), (18, 14), (21, 28), (24, 36)

Enter the above points in a graphing calculator.

From the graphing calculator, we have the following summary:

<u>X Values</u>

  • Sum X = 90
  • Mean = 18
  • ∑(X - Mx)^2 = SSx = 90

<u>Y Values</u>

  • Sum Y = 156
  • Mean = 31.2
  • ∑(Y - My)^2 = SSy = 692.8

<u>X and Y Combined</u>

  • N = 5
  • ∑(X - Mx)(Y - My) = -18

<u>R Calculation</u>

r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))

This gives

r = -18 / √((90)(692.8)) = -0.0721

So, the correlation coefficient is -0.0721

The above is a negative correlation because it is less than 0 and it is a weak correlation because it is closer to 0 than -1

Hence, the correlation is a weak negative correlation
