1)我感觉应该是ratio.
Using a ratio scale permits comparisons such as being twice as high,or one-half as much.
2)open-ended frequency distribution 见下例.
Wages of workers in a factory
Monthly Income (Rs.) ---------- NO.of Workers
Less than 2000/- ---------------- 99
2000-2999/- ----------------- 290
3000-3999/- --------------- 240
4000-4999/- ---------------- 49
5000 & above --------------- 110
因为中数并不落在open ended class,ie:less than 2000,greater than 5000,
这种情况下中数是可求的.
相反,如果把5000 & above的工人数改成1100,则中数落在这个区,那么中数无法求得.
其实很简单,英文把它搞复杂了.
