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~
