A research group is interested in studing the “psychological impacts of sexual abuse in young adults”. They plan to conduct one-on-one interviews with individuals who have been sexually abused as children. The research group has put together an excellent application packet for IRB, however they have not included a consent form. The authors believe that they do not need to use consent forms for this study as most of the individuals are patients/ clients at their medical practice. In your understanding, does this proposed study need a consent form??

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
