bunda:
X – Aholi soni
Y –Har ming kishiga to’g’ri keladigan tug’ulish koeffetsenti %
Yuqoridagi jadvaldan shuni korishimiz mumkinki, Yaponiyada 2001-2020-yillar atrofida tug’ulish koeffensenti past bo’lgan. Bugungi kunda tug’ulish koeffitsiyenti va aholi salmog’i o'rtasidagi korrelyatsiya koeffitsiyenti
Regression Analysis: X versus Y

The regression equation is

X = 1,20E+08 + 861667 Y
S = 370836 R-Sq = 71,6% R-Sq(adj) = 70,0%

Fitted Line: X versus Y



Yaponiyada aholi soni darajasi X va har ming kishiga tug’ulish koeffensenti
Y o’rtasidagi determinatsiya koeffitsiyenti R²=71,6%ga teng. Yaponiyada aholi va tug’ulish koeffensenti o’rtasida bog’lanish 70%.
Natijalarni tahlil qilsak, Yaponiyada tug’ulish koeffensenti va aholi soni yillar òtgani sayin pasayishi kuzatilgan.
