अवधारणा

माध्यिका ज्ञात करने के लिए पहले आँकड़ों को आरोही या अवरोही क्रम में व्यवस्थित कीजिए। 

माध्यिका = [(n/2)th + (n/2 + 1)th]/2

गणना

आरोही क्रम में आंकड़े

2,3,3,4,7,7,8,9,10,12,15,16,20,23 वां पद

माध्यिका = [(14/2)वां पद + (14/2 + 1)वां पद]/2

⇒ (7वां पद + 8वां पद)/2

⇒ (8 + 9)/2

⇒ 8.5

परास = ऊपरी सीमा - निचली सीमा

⇒ 23 - 2

⇒ 21

माध्य = (8.5 + 21)/2

⇒ 29.5/2

⇒ 14.75

∴  उपरोक्त आँकड़ों की माध्यिका और परास का माध्य 14.75 है।
