स्पीयरमैन का कोटि सहसंबंध गुणांक ρ द्वारा दर्शाया गया है
ρ = 1 – [6∑d2/n(n2 – 1)]
d = x और y चर के भुगतान किए गए वस्तुओं के कोटि का अंतर
∑d2 = कोटि अंतर के वर्गों का योग
n = वस्तुओं के युग्मों की संख्या
दिया गया है
∑d2 = ∑(R1 – R2)2 = 21
n = 6
गणना
ρ = 1 – [6 × 21/6(62 – 1)
ρ = 1 – 21/35
ρ = 14/35
∴ कोटि सहसंबंध गुणांक 0.4 है।
