তথ্য হল 3, 10, 10, 4, 7, 10, 5
অনুসৃত সূত্র:
গড় সম্পর্কে গড় বিচ্যুতি
\(∑\rm \frac{|x_{i} - x̅|}{n}\) যেখানে x̅ = গড়
xi = স্বতন্ত্র পদ
n = মোট পদ সংখ্যা
গড় = সমস্ত পদের যোগফল/পদগুলির মোট সংখ্যা
গণনা:
n = একটি তথ্যের মোট সংখ্যা = 7
গড় x̅ = (3 + 10 + 10 + 4 + 7 + 10 + 5)/7 = 7
গড় থেকে গড় বিচ্যুতি = \(∑\rm \frac{|x_{i} - x̅|}{n}\)
গড় থেকে গড় বিচ্যুতি = (1/7) × [4 + 3 + 3 + 3 + 0 + 3 + 2]
∴ গড় বিচ্যুতি = 18/7
