Question

Determine whether the given source has the potential to create a bias in a statistical study.

Brain Size. A data set in Appendix B includes brain volumes from 10 pairs of monozygotic (identical) twins. The data were collected by researchers at Harvard University, Massachusetts General Hospital, Dartmouth College, and the University of California at Davis.

Short answer

No, the source mentioned in the study does not have any scope for bias.

Step-by-step solution

Given information

A study is conducted on ten pairs of identical twins for their recorded brain volumes.

The organizations involved in the collection of data for the study are

• Harvard University,
• Massachusetts General Hospital,
• Dartmouth College, and
• the University of California at Davis.

Explain the bias at the source

No, there is no possibility of a bias in the study.

The study on 10 pairs of twins is based on data gathered by experts from four prestigious institutes. The institutions are internationally renowned and conduct research projects that are critical to individuals.

As a result, the institutions can be relied upon to provide unbiased data for the study.

Thus, there is no possibility of a bias in the study.
