Q.2 (B)(v) If Σ f_i d_i = 10,000 , Σ f_i = 100 and A = 2000 , then find mean (x) .

Answer: x = 2100 x = A + Σ f_i d_i/Σ f_i x = 2000 + 10000/100 = 2000 + 100 = 2100 .

If \(\sum f_i d_i = 10,000\), \(\sum f_i = 100\) and \(A = 2000\), then find mean \((\bar{x})\).

Q.2 (B)(v) If \(\sum f_i d_i = 10,000\), \(\sum f_i = 100\) and \(A = 2000\), then find mean \((\bar{x})\).

Best answer

Answer: \(\bar{x} = 2100\)

\(\bar{x} = A + \dfrac{\sum f_i d_i}{\sum f_i}\)

\(\bar{x} = 2000 + \dfrac{10000}{100} = 2000 + 100 = 2100\).
