The mean deviation about the mean for the following data:
- A \(14.33\)
- B \(15.66\)
- C \(18\)
- D \(23.84\)
Answer & Solution
Correct Answer
(D) \(23.84\)
Step-by-step Solution
Detailed explanation
Mean \((\bar{x})=\frac{\Sigma f_i x_i}{\Sigma f_i}=\frac{2560}{50}=51.2\) Mean deviation about mean \(=\frac{\Sigma f_i\left|x_i-\bar{x}\right|}{\Sigma f_i}\)…
