Bias

Bias has evolved to become a preference in favor of or against a person, group of people, or thing.

Bias can also happen if a sample group lacks inclusivity.

Data bias

Data bias is a type of error that systematically skews results in a certain direction.

We'll explore three more types of data bias:

• sampling bias
• observer bias
• interpretation bias
• confirmation bias

Sampling bias

Sampling bias is when a sample isn't representative of the population as a whole.

A great way to discover if you're working with unbiased data is to bring the results to life with visualizations.

Observer bias

Observer bias is sometimes referred to as experimenter bias or research bias.

Basically, it's the tendency for different people to observe things differently.

Interpretation bias

It's the tendency to always interpret ambiguous situations in a positive, or negative way.

Confirmation bias

It's the tendency to search for, or interpret information in a way that confirms preexisting beliefs.
