Annotatsiya. Ushbu maqolada matematik statistikaning asosiy elementlari –
bosh to‘plam va tanlanma, statistik kuzatish, variatsion qator, chastotalar, statistik
taqsimot, guruhlash hamda statistik baholash –tizimli ravishda tahlil qilindi. Nazariy
qismda mazkur tushunchalarning ilmiy tadqiqotlarda, ishlab chiqarish jarayonlarini
nazorat qilishda va boshqaruv qarorlarini qabul qilishda tutgan o‘rni yoritildi.
Amaliy qism sifatida 50 ta talaba reyting ballaridan iborat ma’lumotlar bazasi
tuzilib, variatsion qator, chastotalar jadvali, arifmetik o‘rtacha, moda, mediana,
dispersiya, standart og‘ish va variatsiya koeffitsienti hisoblandi. Olingan natijalar
ma’lumotlarning nisbatan bir jinsli ekanini va o‘rtacha baho atrofida to‘planganini
ko‘rsatdi.
