दिया गया है

μ'1, μ2, μ'3, μ'4 स्वेच्छ बिंदु आघूर्ण हैं

μ’1 = 2

μ’2 = 136

μ’3 = 320

μ’4 = 40,000

गणना

हमें पहले अपने केंद्रीय आघूर्ण को ज्ञात करना होगा

μ1 = μ’1 = 2

μ2 = μ’2 – (μ’1)2

⇒ 136 – (2)2

136 – 4

⇒ 132

μ3 = μ’3 – 3 × μ’2μ’1 + 2 × (μ’1)3

⇒ 320 – 3 × 136 × 2 + 2 × (2)3

⇒ 320 – 816 + 16

⇒ - 480

μ4 = μ’4 – 4 × μ’1 × μ’3 + 6 × μ’2 × (μ’1)2 – 3 × (μ’1)4

⇒ 40000 – 4 × 2 × 320 + 6 × 136 × 22 – 3 × 24

⇒ 40000 – 2560 + 3264 – 48

⇒ 40656 

विषमता के गुणांक को βके द्वारा दर्शाया जाता है  

⇒ β1 = μ2332

⇒ (-480)2/(132)3

∴ विषमता का गुणांक (-480)2/(132)है।
