Which of the following is TRUE?
a. When preparing data for computer analysis, it is advisable to use alphabetic characters to code the data rather than numbers since alphabetic characters allow 26 codes per column while numbers only allow 10; thus, one can minimize the number of computer records per observation with alphabetic characters.
b. When preparing data for computer analysis, it is advisable to use as few records per observation as possible and thus the use of multiple entries per column is strongly recommended.
c. When a questionnaire requires more columns of code than will fit in a record, researchers should allow for a record sequence number along with a respondent identification number on each computer record.
d. A researcher is coding a variable that has ten possible answers. The researcher needs to provide two columns in the computer record when developing the codebook.
