14-16. The surveys have a bias. (a) Determine the type of bias. (b) Suggest a remedy.

14. A textbook publisher wants to determine what percentage of college professors either require or recommend that their students purchase textbook packages with supplemental materials, such as study guides, digital media, and online tools. The publisher sends out surveys by email to a random sample of 320 faculty members who have registered with its website and have agreed to receive solicitations. The publisher reports that 80% of college professors require or recommend that students purchase some type of textbook package. What is the answer!

Solution

The surveys have response bias,

It is therefore important for researchers to be aware of response bias and the effect can have on their research so that they can attempt to prevent it from impacting their findings in a negative manner.

2. This is a distinct problem for self-report research because it does not allow a researcher to understand or gather accurate data from any type of question that asks for a participant to endorse or reject statements.Researchers have approached this issue by thinking about the bias in two different ways. The first deals with the idea that participants are trying to be agreeable, in order to avoid the disapproval of the researcher. A second cause for this type of bias was proposed by Cronbach, when he argued that it is likely due to a problem in the cognitive processes of the participant, instead of the motivation to please the researcher.He argues that it may be due to biases in memory where an individual recalls information that supports endorsement of the statement, and ignores contradicting information.
