अवधारणा:

विचरण का गुणांक इसके द्वारा दिया जाता है: \(\frac{σ }{{\bar x}} \times 100\) जहां σ मानक विचलन है और \(\bar x\) माध्य है।

गणना:

दिया हुआ: वितरण का माध्य 21 और उसका मानक विचलन 7 है|

यहाँ σ = 7 और \(\bar x = 21\)

जैसा कि हम जानते हैं कि विचरण का गुणांक इसके द्वारा दिया जाता है: \(\frac{σ }{{\bar x}} \times 100\) जहां σ मानक विचलन है और \(\bar x\) माध्य है।

⇒ \(\frac{7 }{{21}} \times 100 = 33.33\)%
