Answer 1

True

Question 2

Answer 2

True

Question 3

Responses can be logically inconsistent.

Answer 3

True

Question 4

Missing value codes should be distinct from the codes assigned to the legitimate responses.

Question 5

At the editing stage,the researcher makes a preliminary check for consistency.

Question 6

The data preparation process begins after the fieldwork is done.

Question 7

The data-preparation process is guided by the preliminary plan of data that was formulated in the research design phase.

Question 8

If possible,standard codes should be used for missing data.

Computer packages like SPSS,SAS,EXCEL,and MINITAB can be programmed to identify out-of-range values for each variable and print related code information to make it easy to check each variable systematically for out-of-range values.

Question 10

When setting up the code book for a questionnaire,you would allow 2 columns to code the response to the question
"Do you have a valid passport? 1.yes 2.no"

The selection of data-transcription method is guided by the type of interviewing method used and the availability of equipment.

Question 12

The following codes should be included for each respondent: project code,interviewer code,date and time codes,category codes,and validation code.
