question 7

Multiple Choice

Robert notices that several respondents did not answer the question of whether they took out loans to fund their education. However, later in his survey, Robert finds that respondents told him about the source(s) and the amount(s) of their college loans. In handling the missing data on the question of whether or not they had a college loan, Robert's best approach is to:

• A)randomly assign values to the missing data.
• B)delete the cases with missing data from the analysis.
• C)assign the middle value to the cases with the missing data.
• D)use the information about amount and source of loans to assign values.
• E)ask the respondents to complete the survey a second time to get accurate responses.
