The most recent meta-analysis establishes that school factors, teacher factors, and external and policy factors are key factors that influence teacher attrition and retention. [1] Teacher attrition is thought to be higher in low income schools and in high need subjects like math, science, and special education. More recent evidence suggests ...

Attrition bias is a kind of selection bias caused by attrition (loss of participants), [13] discounting trial subjects/tests that did not run to completion. It is closely related to the survivorship bias , where only the subjects that "survived" a process are included in the analysis or the failure bias , where only the subjects that "failed" a ...

Attrition is one of the reasons why volcanic ash is very fine-grained. The more attrition erosion the more fine-grained ash produced. [ 27 ] The consequence of this is the disruption of a volcano's geologic stability, varied tephra (rock and particles expelled from the volcano during the eruption), and more particles in the atmosphere affecting ...
Longitudinal studies cannot avoid an attrition effect: that is, some subjects cannot continue to participate in the study for various reasons. Under longitudinal research methods, the reduction in the research sample will bias the remaining smaller sample. [citation needed]
The high dropout rates have provoked neither an internal crisis nor a re-evaluation of programming. Stamper dismissed dropouts as “attrition by personal choice.” An addict’s failure is considered a result of not being ready for treatment, never an indication that there might be a problem with the treatment itself.
Notably, attrition rates varied significantly among different schools, warranting closer scrutiny to establish cause. [9] [10] According to a 2014 study by Jeffe et al., among those MD–PhD program enrollees who either graduated with MD–PhD degrees or withdrew/were dismissed from medical school, certain factors were associated with attrition.
