ধারণা:

সংখ্যাগুরু মান, মধ্যমা এবং গড়ের মধ্যে সম্পর্ক দ্বারা দেওয়া হয়:

সংখ্যাগুরু মান = 3 x মধ্যমা - 2 x গড়

গণনা:

প্রদত্ত:

সংখ্যাগুরু মান - ,মধ্যমা = 2

আমরা জানি

সংখ্যাগুরু মান = 3 x মধ্যমা - 2 x গড়

এখন, সংখ্যাগুরু মান = মধ্যমা + 2

⇒ (2 + মধ্যমা ) = 3 মধ্যমা - 2 গড়

⇒ 2 মধ্যমা - 2 গড় = 2

⇒ মধ্যমা  - গড় = 1

∴ মধ্যমা এবং গড়ের মধ্যে পার্থক্য হল 1।
