What is an outlier in the statistics example?
A value that is outside (much less than or greater than) most of the other values in the input. For example, the values 25, 29, 3, 32, 85, 33, 27, 28, 3, and 85 are outliers.

What is an outlier in statistics?
An outlier is an observation that is abnormally distant from other values in a random sample of the population. … Examine the data for unusual observations that are far from the majority of the data. These points are often called outliers.
How to define an outlier?
By multiplying the interquartile range (IQR) by 1.5, we can determine if a particular value is an outlier. If we subtract 1.5 x IQR from the first quartile, all data values below this number will be considered outliers.
How to find outliers in statistics?
Outlier (name, “outlier”)
This is an observation point or data that is outside the normal range. In scientific studies, an outlier can differ significantly from other data points taken by the scientist. Scientists sometimes extract outliers from their data sets. Outliers can also occur in the real world.

What is the 1.5 IQR rule?
Add 1.5 x (IQR) to the third quartile. Any number above this is an estimated outlier. Subtract 1.5 x (IQR) from the first quartile. Any number below this is an estimated outlier.
How to find outliers with Q1 and Q3?
To build this fence, we take IQR times 1.5, then subtract that value from Q1 and add that value to Q3. This gives us the minimum and maximum number of bets that each observation can be compared to. All observations that are more than 1.5 IQR below Q1 or more than 1.5 IQR above Q3 are considered outliers.
