Bias Types from Wikipedia
A statistic is biased if it is calculated in such a way that it is systematically different from the population parameter being estimated. The following lists some types of biases, which can overlap.
- Selection bias involves individuals being more likely to be selected for study than others, biasing the sample. This can also be termed Berksonian bias.
--Spectrum bias arises from evaluating diagnostic tests on biased patient samples, leading to an overestimate of the sensitivity and specificity of the test. - The bias of an estimator is the difference between an estimator's expected value and the true value of the parameter being estimated.
--Omitted-variable bias is the bias that appears in estimates of parameters in regression analysis when the assumed specification omits an independent variable that should be in the model. - In statistical hypothesis testing, a test is said to be unbiased if, for some alpha level (between 0 and 1), the probability the null is rejected is less than or equal to the alpha level for the entire parameter space defined by the null hypothesis, while the probability the null is rejected is greater than or equal to the alpha level for the entire parameter space defined by the alternative hypothesis.
- Detection bias occurs when a phenomenon is more likely to be observed for a particular set of study subjects. For instance, the syndemic involving obesity and diabetes may mean doctors are more likely to look for diabetes in obese patients than in thinner patients, leading to an inflation in diabetes among obese patients because of skewed detection efforts.
- In educational measurement, bias is defined as "Systematic errors in test content, test administration, and/or scoring procedures that can cause some test takers to get either lower or higher scores than their true ability would merit. The source of the bias is irrelevant to the trait the test is intended to measure."
- Funding bias may lead to the selection of outcomes, test samples, or test procedures that favor a study's financial sponsor.
- Reporting bias involves a skew in the availability of data, such that observations of a certain kind are more likely to be reported.
- Analytical bias arises due to the way that the results are evaluated.
- Exclusion bias arise due to the systematic exclusion of certain individuals from the study.
- Attrition bias arises due to a loss of participants e.g. loss to follow up during a study.
- Recall bias arises due to differences in the accuracy or completeness of participant recollections of past events. e.g. a patient cannot recall how many cigarettes they smoked last week exactly, leading to over-estimation or under-estimation.
- Observer bias arises when the researcher subconsciously influences the experiment due to cognitive bias where judgment may alter how an experiment is carried out / how results are recorded.
Multicultural biases and Education
Definition of antibias: opposing or prohibiting unfair discrimination against people based on race, religion, etc. : preventing or counteracting bias (as in hiring practices) merriam-webster.com/dictionary/antibias
Anti-bias education is an approach to teaching and learning designed to increase understanding of differences and their value to a respectful and civil society and to actively challenge bias, stereotyping and all forms of discrimination in schools and communities.
Multicultural curriculum taught basic facts about different cultures, often on specially designated culture days or holidays, rather than being systematically infused into the entire curriculum. While this did increase students' superficial knowledge of other cultures, educators wanted students to know why they didn't know about other cultures and why certain people of certain ethnicities and classes are less likely to be economically successful.
The objectives of the anti-bias curriculum are to raise awareness of bias and to reduce bias. Anti-bias curriculum transgresses the boundaries by actively providing children with a solid understanding of social problems and issues while equipping them with strategies to combat bias and improve social conditions for all.
Cultural bias is the phenomenon of interpreting and judging phenomena by standards inherent to one's own culture. The phenomenon is sometimes considered a problem central to social and human sciences, such as economics, psychology, anthropology, and sociology. Some practitioners of the aforementioned fields have attempted to develop methods and theories to compensate for or eliminate cultural bias.

Some California preschools are getting children to participate in conversations about racial differences at an early age by introducing an anti-bias curriculum that teaches kids about diversity and inclusion. Against a backdrop of national divides over race, these educators use art projects and discussions to infuse a powerful message into the classroom. Special correspondent Cat Wise reports.
