The following presentation is a revision in preparation for one of the three questions that may asked on Paper 3 for the "mini-essay."  Discuss how the researcher could avoid bias in this study. 

It is important when writing a response to this question that you demonstrate a range of understanding relevant to the concept of bias. In addition, you need to make a direct connection to the study.  Simply writing a generic response on how to avoid bias is not enough to earn high marks.
