Find the mean deviation for the observations – 1, 0, 4. – InterviewSolution

1.	Find the mean deviation for the observations – 1, 0, 4.
Answer» Observations x: – 1, 0, 4 ∴ Mean x̄ = \(\frac{−1+0+4}{3}=\frac{3}{3}\) = 1 Now, Σ\|x – x̄\| = 2 + 1 + 3 = 6 ∴ Mean deviation MD = \(\frac{∑\|x−x¯\|}n=\frac{6}{3}\) = 2
