What is the term for a point that varies greatly from all other data points

Answer 1

The term for a point that varies greatly from all other data points is known as an OUTLIER

Explanation:

• An outlier is a data point that differs significantly from other observations. An outlier may be due to variability in the measurement or it may indicate experimental error.
• An outlier can cause serious problems in statistical analyses.
• An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst to decide what will be considered abnormal.
• A point that falls outside the data set's inner fences is classified as a minor outlier, while one that falls outside the outer fences is classified as a major outlier.
• The data here appear to come from a linear model with a given slope and variation except for the outlier which appears to have been generated from some other model.
• Outliers can occur by chance in any distribution, but they often indicate either measurement error or that the population has a heavy-tailed distribution.
