पाच सलग सम संख्यांची सरासरी = 16
वापरलेले सूत्र:
V = प्रचरण (वेरीयन्स)
∑ = समाकलन
x = निरीक्षण
n = निरीक्षणांची संख्या
a = संख्यामधील प्रथम पद
d = सामायिक फरक
गणना:
⇒ 2a + (5 – 1)2 = 32
⇒ 2a + 4 × 2 = 32
⇒ 2a = 32 – 8
⇒ 2a = 24
⇒ a = 12
प्रथम पद = 12
इतर पद आहेत, 14, 16, 18, 20

⇒ 8
⇒ V = 8
∴ संख्यांचे प्रचरण (वेरीयन्स) 8 आहे.
