Jadvalda keltirilgan ma’lumotlardan foydalanib, natijaviy ko‘rsatkich (N) va
omilli ko‘rsatkichlar (birinchi omil – q; ikkinchi omil –p) urtasidagi boglanishni
analitik ifodalash shaklini aniqlab olishimiz mumkin:
N = q x p
Zanjirli boglanish usulining moxiyatiga kura hisoblarni quyidagi tartibda
amalga oshirishimiz mumkin:
1 – hisob: 5000 x 76,0 = 380.000,0 – (-
15200,0)
2 – hisob:
4800 x 76,0 = 364800,0
– (
+19200,0)
3 – hisob: 4800 x
80,0 = 384000,0
Qilingan hisoblardan ko‘rinib
turibdiki, zanjirli
boglanish usuli yordamida
omillar ta’sirini ularni navbatma navbat almashtirish orqali amalga oshiriladi.
Bunda bir omil ta’sirini aniqlayotgan vaktda, ikkinchi omilni o‘zgarmas kilib olish
lozim.

Zanjirli boglanish usulining soddalashtirilgan usuli bu tafovutlar usulidir.
Uni yordamida omillar ta’siri quyidagicha hisoblanishi mumkin:
