This encoding scheme of the questionnaire could have the following appearance 6 (see Figure 2): questionnaire ID. (> code: id) F.: 1 gender of the respondent: (> code: sex)? female, (> code: 1)? male, (> code: 2)? no details (> code: 0) 2. Please will you tell me your age? __ Years (> code: old) 3 4 know you the bio-Hof XY? (> Code: hof)? Yes, (code: 1)? No (> code: 2) 5 6. We have talk now about this bio tuber. If you could buy this tuber, what were you ready for this tuber in to spend? _ (Code: zahlg) 07 figure 2: encoding scheme of the questionnaire the codes can in IBM SPSS contain up to 64 characters. For the clarity in the system with its tables it is advisable however as short as possible,”assigning codes. The characters in the code can be letters (Uppercase and lowercase), numbers, or special characters. The sign _ “or.” as the last character and a space and AND, ALL BY EQ, GE, GT, LE, LT, NE, should not be used WITH, TO, OR, emergency.
For the possible characteristics on the questionnaire you awards for reasons of practicality numbers as codes (ideally an ascending number sequence). When entering data into the system, the corresponding code is entered depending on the characteristic value on the questionnaire. No codes must be designed for metric characteristics (for example, age or willingness to pay). When entering data into the system, the specific number from the questionnaire is entered. Through this work, simplifies data collection and data analysis in the system and speed up. 4.
work with IBM SPSS, variable view, data view 4.1. transfer encoding in the system, variable view, labels, measuring levels of the farmer has now set his encoding scheme and will enter this and the data on the questionnaires in IBM SPSS. To do this, he calls the program IBM SPSS statistics.
