Selection Bias Types There are many types of selection bias, each and every one of them impacting the validity of your data in a specific way. Let’s go over some of the most common ones: Sampling Bias: Sampling bias is a form of selection bias that occurs when we don’t collect dat...
5. How to Prevent Selection Bias 5.1. Review the Literature Now that we understand what selection bias is and how it can influence our statistical analysis, it’s time to consider what methods are available to prevent it. In some cases full prevention may be impossible: in that case, reduci...
However, these surveys suffer from self-selection bias, because those who feel animated enough by the topic to participate are more likely to do so. Additionally, it is very challenging to verify that respondents really belong to the intended population. For example, there is no way to easily ...

Machine learning bias, also known asalgorithmbiasorAI bias, is a phenomenon that occurs when an algorithm produces results that are systemically prejudiced due to erroneous assumptions in the machine learning (ML) process. Machine learning, a subset of artificial intelligence (AI), depends on ...
