What does it mean when an article is biased?
Bias means that a person prefers an idea and possibly does not give equal chance to a different idea. Facts or opinions that do not support the point of view in a biased article would be excluded. For example, an article biased toward riding a motorcycle would show facts about the good gas mileage, fun, and agility.
What are some examples of biases?

- Affinity Bias.
- Confirmation Bias.
- Attribution Bias.
- Conformity Bias.
- The Halo Effect.
- The Horns Effect.
- Contrast Effect.
- Gender Bias.
Can Rcts be biased?
A major and common source of bias in an RCT is selective report- ing of results, describing those outcomes with positive results, or which favor the studied intervention. This is not always con- sciously done. The investigator may even unconsciously be attracted more to certain outcomes than others.
How can we prevent detection bias?
To avoid detection bias, it is important to at least attempt single-blind outcome assessment. Obviously, double-blind studies have greater protection against bias than single-blind studies, but single-blinding is better than no blinding at all.
What is single blinding?
: of, relating to, or being an experimental procedure in which the experimenters but not the subjects know the makeup of the test and control groups during the actual course of the experiments — compare double-blind, open-label.
What is a blinding?
1 : causing or seeming to cause blindness : making sight difficult or impossible a blinding light a blinding snowstorm a blinding headache [=an extremely painful headache]
What is the difference between single blind and double-blind studies?
In a single-blind study, patients do not know which study group they are in (for example whether they are taking the experimental drug or a placebo). In a double-blind study, neither the patients nor the researchers/doctors know which study group the patients are in.
Why is a single blind study used?
In a single blind study, the participants in the clinical trial do not know if they are receiving the placebo or the real treatment. This is done to reduce the risk of errors, since some participants might produce spurious results if they know that they are taking the placebo or medication.

Why do we use single and double blind studies?
A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.
What is the fairest way to take a representative sample from a population?
Which is the fairest way to take a representative sample form a population? ensuring that every subject in the population has an equal chance to be selected.
Can a well designed experiment be replicated by others?
Placebos are sometimes used in research in order to demonstrate the effects of participant expectations or beliefs on the outcome of behavior. A well-designed experiment can be replicated by others. Convenience sampling can produce biased research results.
Can convenience sampling can produce biased research results?
Answer Expert Verified Convenience sampling is one of the non-probability type of sampling methods. This technique involves test subjects that are selected due to convenience and accessibility to the researcher. Therefore, the sampling is limited to only a certain group and can produce biased research results.
