Chapter 1: Q5BSC (page 1)

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

Physicians Committee for Responsible Medicine. The Physicians Committee for Responsible Medicine tends to oppose the use of meat and dairy products in our diets and that organization has received hundreds of thousands of dollars in funding from the Foundation to Support Animal Protection.

Short Answer

Expert verified

Yes, there is a potential for bias in the study.

Step by step solution

01

Given information

The physicians’ committee is against the use of meat and dairy products.

Also, the organization is known to have received funding from a foundation that supports animal protection.

02

Explain the bias at the source

Yes, there are chances of bias in the study.

A group of physicians, financed largely by an animal protection organization, conducted the research to oppose the usage of animal products, like meat and different dairy products in diets.

Since meat and dairy products are produced from animals, there is a significant possibility that the study will be biased. The committee is likely to favor the funding group and hence have skewed opinions on animal-derived goods.

Thus, there is a potential for creating bias in the study.

In Exercises 21–24, refer to the data in the table below. The entries are white blood cell counts (1000 cells,ML) and red blood cell counts (million cells,ML) from male subjects examined as part of a large health study conducted by the National Center for Health Statistics. The data are matched, so that the first subject has a white blood cell count of 8.7 and a red blood cell count of 4.91, and so on.

Conclusion: If we analyze the sample data and conclude that there is a correlation between white blood cell counts and red blood cell counts, does it follow that higher white blood cell counts are the cause of higher red blood cell counts?
