భావన :

వైవిధ్యం యొక్క గుణకం దీని ద్వారా ఇవ్వబడుతుంది: \(\frac{σ }{{\bar x}} \times 100\) ఇక్కడ ప్రామాణిక విచలనం మరియు \(\bar x\) సగటు.

లెక్కింపు :

ఇచ్చినవి: పంపిణీ యొక్క సగటు 21 మరియు ప్రామాణిక విచలనం 7.

ఇక్కడ, σ = 7 మరియు \(\bar x = 21\)

వైవిధ్యం యొక్క గుణకం ఇచ్చినట్లు మనకు తెలుసు: \(\frac{σ }{{\bar x}} \times 100\) ఇక్కడ ప్రామాణిక విచలనం మరియు \(\bar x\) సగటు.

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