As humans, our brains are designed to be biased no matter hard; we try to make sure that everything works better for the statistics. If you have a biased statistics, you have bad statistics. It is important one tries to make sure that they know their statistical bias types which work on the types of bias which can help affect the result.

Selection bias

Selection bias occurs when you are selecting the right sample, which can help one analyse the data wrong. This means that they can accidentally work with the specific subset of your audience instead of the whole, which can lead to being unrepresented from the population. There are many underlying reasons but can be easily accessed.

Self-selection bias

Self-selection bias is another category of selection bias in statistics. This is where the subject analyses select themselves, which can lead to less proactive, which will be excluded. The bigger issue is that self-selection is a specific behaviour which can help correlate with the other specific behaviour. This does not represent the whole population but still has variety.

Recall bias

Recall bias is another common error which occurs during the whole process of interview and survey situation. It is about good or bad memory which can have selective memory by default which can stay or fade. It is normal, which can make for a difficult for further research.

Observer bias

Observer bias happens when the researcher subconscious projects, which matches the expectations of the research. This can be unintentional influencing participants which can be by picking the perfect people for the research.

Survivorship bias

Survivorship bias is a statistical bias is where the researcher focuses on the part where the data set is already with some kind of pre-selection process without missing on those data points which can help with the whole process.

Omitted variables bias

Omitted variable bias occurs when you are leaving out for the variables which do not match your model. This issue comes up, especially which often is regarded as predictive analytics. This is the model which works on the concept of the ‘what happened in the past will happen in the future.’ These models are very vulnerable, which is often complicated in their predictions and can cause a lot of inaccuracy.

Cause effect Bias

Cause effect bias is usually is not mentioned to be a part of classic statistical bias which can help ensure that they can make decisions regarding business, marketing and managers. This can help give them a reminder of the correlation does not imply caution and can be used to take the right steps to make sure that your business is taken in the right direction.
