A trade school would like to measure the long-term success of its graduates after they leave the school, and emails a survey requesting information from graduates about their work experience. One question asks graduates if they are currently employed in the field they studied in school, while another asks them to share their annual salary. What type of bias is most likely to be present in the survey results? This is response bias because some graduates may not provide accurate information.

This is question wording bias because many graduates may misunderstand the questions asked.

This is voluntary response bias because graduates may choose to be part of the sample.

This is nonresponse bias because many graduates may choose not to respond to the email survey.
