nonbiased

Nonbiased is an adjective describing something not influenced by prejudice or expectation; impartial; fair; in many contexts, the more common form is unbiased or impartial; nonbiased is found in older or formal texts and in some technical contexts.

In journalism and public discourse, nonbiased reporting is ideal but debated; many media organizations follow standards to present multiple perspectives, disclose conflicts of interest, and rely on verifiable sources to reduce bias.

In statistics and research, unbiased denotes an estimator whose expected value equals the parameter; e.g., the sample mean is unbiased for the population mean under certain conditions. However, absence of bias in design does not guarantee accuracy due to variance or systematic error; bias can arise from sampling, measurement, or model assumptions.

In machine learning and data science, fairness concerns focus on reducing bias in data and models; terms like unbiased, bias-aware, or debiased are used; many practitioners prefer precise terms such as "unbiased estimator", "unbiased classifier" but recognize that real-world data can be imperfect, so debiasing and auditing are applied.

Spelling note: nonbiased is less common; standard adjectives are unbiased or impartial. When clarity is needed, prefer unbiased.
