Anomalous data is data that doesn't fit with the rest of the set. Ex: In week one the tree was 2ft. tall , in week two the tree was 6ft. tall, and in week three the tree was 5ft. tall. Week two would be the anomalous data because it doesn't fit with the other data. I hope this helps!
Anomalous Data
Why do you include an anomalous result in a piece of data
Data that does not fit with the rest of the data set.
Any anomalous data for which there is a clear, external explanation.
You should exclude the anomalous results when calculating an average.

a piece of data which is different to the others x
Yes.
One that does NOT follow the general trend of data. e.g. 1,2,3,4, 8. Eight(8) would be a anomalous value.
An Outlier; an Outlier is when a point is not part of a trend (pattern)
Anomalous data points on a graph are commonly referred to as "outliers." These are values that deviate significantly from the overall trend or pattern of the dataset, often indicating variability in the measurement or potential errors. Identifying outliers is crucial for data analysis, as they can influence statistical results and interpretations.
Data may be anomalous due to errors in data collection, such as incorrect measurements or data entry mistakes, which can lead to outliers that do not reflect the true underlying patterns. Additionally, genuine changes in the environment or underlying processes, such as sudden shifts in consumer behavior or system failures, can result in data points that diverge significantly from established trends.
