पियरसन का विषमता का माप = 0.42
माध्य = x̅ = 86
माध्यिका = Md = 80
सूत्र
विषमता = Skp = 3(माध्य – माध्यिका)/मानक विचलन
गणना
0.42 = 3(x̅ - Md)/σ
⇒ 0.42 = 3(86 – 80)/σ
⇒ σ = 18/0.42
⇒ σ = 300/7
भिन्नता का गुणांक = मानक विचलन/माध्य = (σ/x̅) × 100
⇒ CV = (300/7/86) × 100
⇒ (300/7 × 86) × 100
∴ भिन्नता का गुणांक 50 है
