比如有两个问题是：
1. What proportion of non-managerial employees at this workplace are eligible for the
employee share ownership scheme(s)?
INTERVIEWER: If respondent gives answer as an exact number you can code “97”
here and record the number at the next question
1) All All (100%),
2) Almost Almost all (80-99%),
3) Most Most (60-79%),
4) Half Around half (40-59%),
5) Some Some (20-39%),
6) Few Just a few (1-19%),
7) None None (0%),
97) Number
{If giving exact number}
2.(How many non-managerial employees at this workplace are eligible for the
employee share ownership scheme(s)?)
ENTER NUMBER
Range: 1..999997

这两个问题问的关于同一个的，但是一个是code为百分比的scale，一个是具体的数字。
我想用这两个问题一起来measure同一个东西。这两个是要转换一下还是做factor analysis？
做factor analysis的话，两道问题完全不能放在一块儿。这种情况要怎么处理啊？
谢谢~
