Answer:
Correct Answer: The sample size is not representative of the population
Explanation:
Bias in a scientific study can be said to occur when there is a prejudice for or against one person or group, especially in a way considered to be unfair.
For example, in a society that tries to promote the relationship between Christians and Muslims in a work place. In a study carried out to determine how this relationship could be achieved by a researcher, if he or she happens to have prejudice against one of the group, it would definitely affects his research outputs and results.
