How do you find a outlier in math?
Multiplying the interquartile range (IQR) by 1.5 will give us a way to determine whether a certain value is an outlier. If we subtract 1.5 x IQR from the first quartile, any data values that are less than this number are considered outliers.
What is outlier in simple words?
A value that “lies outside” (is much smaller or larger than) most of the other values in a set of data. For example in the scores 25,29,3,32,85,33,27,28 both 3 and 85 are “outliers”.

Sorting your values from low to high and checking minimum and maximum values.Visualizing your data with a box plot and looking for outliers.Using the interquartile range to create fences for your data.Using statistical procedures to identify extreme values.
What is a gap in math?
Gaps refer to missing areas in a data set. For example, if a scientific experiment collects temperature data in the range of 50 degrees Fahrenheit to 100 degrees Fahrenheit, but nothing between 70 and 80 degrees, that would represent a gap in the data set.
