दिया गया है:

आंकड़ें 3, 10, 10, 4, 7, 10, 5 है।

प्रयुक्त सूत्र:

माध्य से औसत विचलन

\(∑\rm \frac{|x_{i} - x̅|}{n}\) जहाँ x̅ = माध्य

xi = अवयवी पद

n = पदों की कुल संख्या

माध्य = सभी पदों का योग/पदों की कुल संख्या

गणना:

n = आँकड़ों में कुल संख्या = 7

माध्य x̅ = (3 + 10 + 10 + 4 + 7 + 10 + 5)/7 = 7

माध्य से माध्य विचलन = \(∑\rm \frac{|x_{i} - x̅|}{n}\)

माध्य से माध्य विचलन = (1/7) × [4 + 3 + 3 + 3 + 0 + 3 + 2]

∴ माध्य विचलन = 18/7
