What is a common characteristic of biased samples?

A common characteristic of biased samples is that they often misrepresent the views or behaviors of the population. This occurs because biased samples are not representative of the entire population due to factors such as over-representation or under-representation of certain groups. For example, if a sample is drawn primarily from a particular demographic, like age or socio-economic status, it can lead to skewed results that do not accurately reflect the diverse perspectives within the broader population. This misrepresentation is a critical concern in research and statistics, as it can lead to incorrect conclusions and decisions made based on faulty data.
