*^*Bu erda s² ning (n-1) bo’luvchi bilan hisoblanishi, σ² ning siljimagan bahosi hisoblanadi.
^s² ni hisoblashda necha o’nli kasrgacha yaxlitlanishi kerak? Bu borada yaxlitlash to’g’risida aniq qoida bo’lmaganligi sabali, zarur bo’ladigan natijadan ikki barobar ko’p darajagacha yaxlitlash zarur. Masalan, siz s ning aniqlik darajasi yuzdan birgacha yaxlitlikda chiqishini istasangiz, s² natijasi mingdan bir darajagacha (to’rt xonagacha) yaxlitlash zarur.
