通过点计数进行模态分析有三个主要的误差来源：(a)算子变化，(b)通过网格计数确定面积，(c)通过面积分析确定体积。算子的变化可能是可以忽略不计的，但(b)和(c)可以结合起来给出一个等于或小于其中a=测量面积，a=网格间距，R=颗粒半径，p=岩石中特定矿物的分数的方差（Hasofer, 1963）。
There are three principal sources of errors involved in modal analyses by point counting: (a) operator variation, (b) the determination of area by grid counting, (c) the determination of volumes from areal analyses.Operator variation is likely to be negligible but (b) and (c) may combine to give a variance equal to, or less thanwhereA=measurement area,a=grid spacing,R=grain radius, andp=the fraction of the particular mineral in the rock (Hasofer, 1963).
