Preferred Name	Bias
Definitions	Any deviation of results or inferences from the truth, or processes leading to such deviation. Bias can result from several sources: one-sided or systematic variations in measurement from the true value (systematic error); flaws in study design; deviation of inferences, interpretations, or analyses based on flawed data or data collection; etc. There is no sense of prejudice or subjectivity implied in the assessment of bias under these conditions.
Synonyms	Systematic Bias Biases, Ecological Outcome Measurement Errors Bias, Statistical Bias, Experimental Biase, Epidemiologic Fallacy, Ecological Bias, Aggregation Bias, Scientific Biases Ecological Bias Bias, Truncation Scientific Bias Biases, Statistical Statistical Bias Ecological Fallacies Biases, Truncation Truncation Biases Fallacies, Ecological Bias, Ecological Aggregation Bias Truncation Bias Biases, Epidemiologic Statistical Biases Bias, Epidemiologic Errors, Outcome Measurement Outcome Measurement Error Ecological Biases Bias, Systematic Epidemiologic Biase Ecological Fallacy Epidemiologic Biases Experimental Bias Error, Outcome Measurement See more See less
