Spoce limitations may restrict the number of categories in mail questionnaires. If teleghone intenviews are involved, many categories may confuse the respondents. All of the statement above are true.

Answer 1

Explanation:

All the statements above are true.

- More categories can be used if the respondent is interested in scaling tasks and has knowledge of the object being evaluated. This allows respondents to get more differentiated and accurate answers.

- Space limitations in email surveys may limit the number of categories you can include. Due to space limitations, it may be necessary to use a smaller number of categories to fit your survey layout. - In telephone interviews, too many categories can confuse respondents. Due to the lack of visual cues, it can be difficult for respondents to distinguish between numerous categories on the phone. Using fewer categories in cases like this provides clarity and a simpler answer.

Therefore, all three statements are true and illustrate different considerations in determining the number of scale categories for a non-comparative single rating scale.
