O'lchov shkalalari

Aholini parametrlarini ifodalash uchun nomalumlik, tartib, masofa va nisbat xususiyatlariga ega bo'lgan o'lchov shkalasi tanlanadi
Agar o'zgaruvchining ikkita qiymati uchun nisbat emas, masofa va tartib muhim bo'lsa, interval o'lchov shkalasi qo'llaniladi
Agar o'zgaruvchining ikkita qiymati uchun ular orasidagi masofa, tartibi va munosabatlari muhim bo'lsa, ratio o'lchov shkalasi qo'llaniladi
Agar o'zgaruvchining ikkita qiymati uchun ular orasidagi nisbat yoki masofa emas, balki faqat ularning tartibi muhim bo'lsa, ordinal o'lchov shkalasi qo'llaniladi
Agar o'zgaruvchining har qanday ikkita qiymati uchun ularning tartibi, munosabatlari yoki ular orasidagi masofa ma'noga ega bo'lmasa, nominal o'lchov shkalasi qo'llaniladi
'Talaba bilimini baholash' o‘zgaruvchisiga ordinal o'lchov shkalasi qo‘llaniladi, chunki 'A (a’lo)', 'B (yaxshi)', 'C (qoniqarli)' va 'D (qoniqarsiz)' qiymatlari orasidagi tartib muhim bo'ladi
