⇒ গড় = (36 + 28 + 45 + 51) / 4 = 160/4 = 40
প্রতিটি পদ এবং গড়ের মধ্যে পার্থক্যের বর্গের গড় গ্রহণ করে ভেদাঙ্ক গণনা করা হয়,
⇒ ভেদাঙ্ক = [(36 - 40)2 + (28 - 40)2 + (45 - 40)2 + (51 - 40)2]/4
= [16 + 144 + 25 + 121] / 4 = 306/4 = 76.5
∴ প্রদত্ত সংখ্যাগুলির ভেদাঙ্ক = 76.5Last updated on Jul 18, 2025
