Table 3: Result details and calculation.
| X Values ∑ = 30 Mean = 1.25 |
| ∑ (X - Mx)2 = SSx = 24.5 |
| Y Values ∑ = 80 Mean = 3.333 |
| ∑ (Y - My)2 = SSy = 59.333 |
| X and Y Combined |
| N = 24 ∑ (X - Mx) (Y - My) = -3 |
| R Calculation |
| r = ∑ ((X - My) (Y - Mx))/√((SSx)(SSy)) |
| r = -3/√((24.5) (59.333)) = -0.0787 |
| Meta Numerics (cross-check) |
| r = -0.0787 |
X: X Values; Y: Y Values; Mx: Mean of X Values; My: Mean of Y Values; X - Mx & Y - My: Deviation scores; (X - Mx)2 & (Y - My)2: Deviation Squared; (X - Mx) (Y - My): Product of Deviation Scores.
