Introduction to trend, anomaly, outlier, divergence, norm, benchmark, threshold, and indicator.
When you analyse datasets in Science or Social Science, you first look for the norm—the expected or typical behaviour of the data. To measure performance, researchers establish a benchmark, which is a standard point of reference. Over time, the general direction in which data moves establishes a clear trend.

Over the last decade, Mumbai's average annual rainfall has gradually decreased, yet July 2023 saw a single record-breaking downpour. The gradual decrease over ten years represents a general direction of change, making it a clear . Meanwhile, the sudden July downpour deviates significantly from expected seasonal patterns, so we classify it as an . In another scenario, a Class 10 Mathematics exam saw most students scoring between 40 and 85 marks, while one student scored a 98. The typical score range of 40 to 85 establishes the for the class's overall performance. The single score of 98 lies completely detached from the main cluster of data, making it a statistical .

Analyzing poverty data over the last decade reveals a declining in rural areas due to government employment schemes. While studying Mendelian genetics, any offspring trait that completely defies the laws of inheritance might be considered a genetic caused by mutation. Per capita income is a key economic used by the World Bank to classify countries as developed or developing. In an ecosystem, if the concentration of a toxic pesticide crosses a critical , it can lead to biomagnification and severe ecological damage. In evolutionary biology, homologous organs like the forelimbs of humans and bats illustrate evolutionary , showing adaptation to different environments.
