संकल्पना :

भिन्नतेचा गुणांक द्वारे दिला जातो: \(\frac{σ }{{\bar x}} \times 100\) जेथे σ हे मानक विचलन आहे आणि \(\bar x\) मध्य आहे.

गणना :

दिलेले: वितरणाचा मध्य 21 आहे आणि मानक विचलन 7 आहे.

येथे, σ = 7 आणि \(\bar x = 21\)

आपल्याला माहित आहे की भिन्नतेचा गुणांक द्वारे दिलेला आहे: \(\frac{σ }{{\bar x}} \times 100\) जेथे σ हे मानक विचलन आहे आणि \(\bar x\) मध्य आहे.

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