VARIATSIYA KO'RSATKICHLARI: NAZARIYA VA AMALIYOT
https://doi.org/10.5281/zenodo.14955729
Abstract
Ushbu maqolada variatsiya ko‘rsatkichlari, ya’ni dispersiya, standart og‘ish, variatsiya koeffitsienti va interkvartil oralig‘ining nazariy asoslari va amaliy qo‘llanilishi ko‘rib chiqilgan. Variatsiya ko‘rsatkichlari ma’lumotlar to‘plamining tarqalishini o‘lchashda va o‘zgaruvchilarning farqlarini aniqlashda muhim rol o‘ynaydi. Dispersiya va standart og‘ish o‘zgaruvchilarning o‘rtacha qiymatdan qanchalik farqlanishini o‘lchasa, variatsiya koeffitsienti nisbiy o‘zgaruvchanlikni, interkvartil oralig‘i esa markaziy ma’lumotlarning tarqalishini ko‘rsatadi. Ushbu ko‘rsatkichlar iqtisodiyot, tibbiyot va ijtimoiy fanlar kabi sohalarda ma’lumotlarni tahlil qilish va qarorlar qabul qilishda keng qo‘llaniladi. Maqolada har bir ko‘rsatkichning afzalliklari va kamchiliklari, shuningdek, ularning amaliy ahamiyati muhokama qilingan.
