How frequent is selection bias? What could be some examples of “recall bias”?

1. Write a summary that includes:

(A) A list of the different type of research bias. Provide some examples from the Internet.

(B) A list of the most common confounders. From the list, pick two and explain how these confounders could affect the research results. In general, what are the most common confounder factors?

(C) A description of the concept of random error and what factors need to be taken into consideration to avoid random error in research.

2. Write a reflection that integrates the concepts discussed above and how these factors affect research results. Some questions that may help you with the preparation of this reflection are:

(a) How frequent is selection bias? What could be some examples of “recall bias”?

(b) What are the most common study confounders?

(c) Why is random error a problem found in some studies? How is it that, sometimes, even mature investigators commit the random error mistake in their research studies?

3. As a conclusion in your discussion, write a brief statement of what you have learned while preparing this discussion and how this exercise will benefit you in your future career in public health.
