3-laboratoriya ishi Juftlik regressiyaning chiziqli tenglamasi. Chiziqli regressiya koeffitsientlarining statistik tahlili. Laboratoriya ishi uchun topshiriqlar: Ishonchli manbalardan hajmi kamida 20 ta bo‘lgan X va Y ma’lumotlar oling. Ushbu ma’lumotlar orasidagi bog‘lanishni aniqlang. Nuqtaviy diagrammasini chizing. Nuqtaviy diagramma asosida xulosa chiqaring. Korrelyatsiya koeffitsiyentini toping. Chiziqli regressiya modelini quring. Determinatsiya koeffitsiyentini aniqlang va ma’nosini tushuntiring. Qurilgan model yordamida bashorat qiling. Ushbu bashorat uchun 95% ishonchlilik bilan bashorat va ishonch oraliqlarini toping. Olingan natijalar asosida umumiy xulosa chiqaring. .
ta’sir ko‘rsatishini o‘rganish va oddiy regressiya tenglamasini tuzish masalasi qaralsin. Bu regressiya tenglamasi yordamida berilgan qiymat uchun bashorat qilinsin va bashorat qiymati uchun ishonch va bashorat intervallari topilsin. 2.1-jadval
