The group of issues Dr.Klassen should pay most attention to are representative sampling, self-report bias, and response set. Representative sampling is important in order to obtain a sample that accurately reflects the population of interest. Self-report bias refers to the tendency for some individuals to respond to survey questions in a way that is socially desirable, rather than truthful. Response set refers to the tendency for participants to respond to all survey items in a similar way, regardless of the content of the item. These issues are important to consider in order to ensure that the results of the survey are accurate and valid.
