Detailed Solution
Download Solution PDFसंकल्पना:
माध्य से माध्य विचलन =
माध्य विचलन का गुणांक =
जहां N प्रेक्षण की संख्या है
x̅ आंकड़ों का माध्य है
x प्रेक्षण का मान है।
गणना:
⇒ x̅ =
माध्य से विचलन का योग Σ∣xi − x̅∣ द्वारा दिया जाता है
⇒ Σ∣xi − x̅∣ = ∣21 − 30∣ + ∣34 − 30∣ + ∣23 − 30∣ + ∣39 − 30∣ + ∣26 − 30∣ + ∣37 − 30∣ + ∣40 − 30∣ + ∣20 − 30∣ + ∣33 − 30∣ + ∣27 − 30∣
⇒ Σ∣xi − x̅∣ = 9 + 4 + 7 + 9 + 4 + 7 + 10 + 10 + 3 + 3
⇒ Σ∣xi − x̅∣ = 66
माध्य से माध्य विचलन =
माध्य विचलन का गुणांक =
∴ माध्य विचलन का गुणांक = 0.22
