Describe how the credibility in science is maintained.
Credibility in science maintained through the correct use of scientific methods, honesty, objectivity, transparency, allowing replication of research, welcoming criticism, and adhering to guidelines for good research practice.
What is the difference between a prospective cohort study and a randomized controlled trial (RCT)?
In a prospective cohort study, the population at risk is divided into groups based on exposure (e.g., potato consumption) to observe outcomes and associations, while an RCT involves random assignment of participants to different interventions to assess causality.
How does science encourage self-correction and critical thinking among researchers?
Science promotes self-correction by allowing replication of research, welcoming criticism, and fostering a culture of doubt and critical debate among scientists.
Define confounding in research studies.
Confounding in research studies refers to a situation where an extraneous variable influences the relationship between the independent and dependent variables, leading to misleading conclusions.
Describe the process of random assignment in a randomized controlled trial.
In a randomized controlled trial, people are randomly assigned to different groups to minimize bias and ensure that each group is comparable.
Define the concept of bias in a study design.
Bias in a study design refers to imperfections that can affect the results, such as dropouts or confounding variables, leading to inaccurate conclusions.
How are impact factors important in scientific articles?
Impact factors are crucial in scientific articles as they indicate the influence and reach of a journal, often used to evaluate the significance of research published.
Do foams cells play a role in cleaning up LDL-cholesterol?
