Anomaly, or abnormality, refers to something that deviates from what is standard, normal, or expected. In various fields, such as medicine, statistics, and science, anomalies can indicate unusual patterns or behaviors that may require further investigation. For example, in medical diagnostics, an anomaly in test results might suggest a potential health issue. In statistics, an anomaly can be an outlier, which is a data point that significantly differs from other observations. Identifying anomalies is crucial as they can provide insights into underlying problems or trends. Understanding these irregularities helps researchers and professionals make informed decisions and improve outcomes.
