Question
Which of the following best describes a source of bias in a sample? A non-random sample Lack of research funding A random sampleFailure to obtain ethics approval
Solution
The best description of a source of bias in a sample from the options provided is a non-random sample.
Here's why:
-
A non-random sample: This is a source of bias because it may not represent the entire population accurately. In a non-random sample, some members of the population may have a higher or lower chance of being included in the sample, which can lead to bias.
-
Lack of research funding: While this can affect the quality and scope of a study, it is not a direct source of bias in a sample.
-
A random sample: This is actually a method used to prevent bias. In a random sample, every member of the population has an equal chance of being included in the sample.
-
Failure to obtain ethics approval: This is a serious issue in research, but it does not directly cause bias in a sample. It could lead to other problems, such as the study being disregarded by the scientific community, but it does not cause bias in the sample itself.
