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.

Answer

# Brief Explanations: The school emails a survey. Many graduates may choose not to respond. Those who do respond may have different characteristics than non - responders, leading to nonresponse bias. Response bias is about inaccurate info from responders, question - wording bias is about question clarity, and voluntary response bias is when people self - select to participate in a different way (e.g., calling in to a radio show). Here, the main issue is non - participation. # Answer: This is nonresponse bias because many graduates may choose not to respond to the email survey.
