TRUNCATION BIAS Meaning and
Definition
-
Truncation bias refers to a type of selection bias that occurs in statistical studies or data analysis when a sample or dataset is inadvertently limited or truncated due to certain factors or criteria. This bias arises when certain observations or data points are missing or excluded from the analysis, leading to incomplete or biased results.
Truncation bias is commonly observed when studying a specific population or group, as data collection or sampling techniques may unintentionally exclude certain individuals or cases. This can introduce bias and affect the generalizability or accuracy of the findings. For example, if a survey on the impact of a new educational program is conducted only among students who completed the program, the results may not account for those who dropped out or did not participate, leading to an overestimation of the program's success.
Truncation bias can also occur in observational studies when certain variables or outcomes are limited or excluded from analysis due to data unavailability, measurement limitations, or deliberate exclusion. This may result in misleading or incomplete conclusions about the relationship between variables.
To mitigate truncation bias, researchers must carefully consider and aim to minimize any unintentional exclusions or limitations in data collection, sampling, or analysis. It is important to ensure that the sample or dataset represents the target population as accurately as possible to avoid biased results and draw valid conclusions.

Etymology of TRUNCATION BIAS
The word "truncation" comes from the Latin word "truncatus", which means "to cut off" or "to maim". In English, "truncation" refers to the act of shortening or cutting something, often by removing a part of it.
The term "truncation bias" is a combination of the word "truncation" and "bias". "Bias" refers to a systematic deviation from truth or accuracy in judgment or decision-making. In the context of scientific research and statistics, "bias" refers to a systematic error or distortion in data collection, analysis, interpretation, or reporting that leads to incorrect or misleading results.
Therefore, "truncation bias" indicates a systematic error or distortion in research or statistical analysis that arises from the act of truncating or cutting off data or observations in a way that skews the results or conclusions.
