There is no agreed definition of an outlier. There are some definitions based on the median (Q2) and the quartiles Q1, and Q3.
Let the inter-quartile range, IQR = Q3 - Q1.
A number is a n outlier if it is:
- less than Q1 - k*IQR or
- greater than Q3 + k*IQR.
A popular choice for k is 1.5

How do you determine how the outlier affects the mean median mode and range?
Calculate the mean, median, and range with the outlier, and then again without the outlier. Then find the difference. Mode will be unaffected by an outlier.
How do you find the outlier in a box and whiskers plot?

How do you use the word outlier in a sentence?
An outlier is an outlying observation that appears to deviate markedly from the other members of a given sample. Outliers can occur by chance.
What is the use of geometric mean?
Find the use in the following link: "Calculation of the geometric mean of two numbers".
Would a mean be smaller or larger if you leave out an outlier?
Depends on whether the outlier was too small or too large. If the outlier was too small, the mean without the outlier would be larger. Conversely, if the outlier was too large, the mean without the outlier would be smaller.
