The most important thing to use is the brain. Why the outlier? Is it more likely to be a genuine result or a data error. Sometimes other variables may suggest a true value.
If you cannot tell then carry out the analysis with a smaller weight associated to the outlier. Carry out a sensitivity analysis to see how much difference including the value as normal (w = 1) and excluding it (w = 0) makes. Report on these differences in the conclusion.

When should an outlier be used?
whenever it can be
Is Median an outlier?
No, median is not an outlier.
Can a outlier be zero?
0s are not the outlier values
Why should outliers generally be excluded when interpreting the relationship of the variables?
The assumption in the question is not valid. There are two main reasons for outliers: one is that there is a measurement or recording error and if that is the case, then the outlier should be excluded. However, it is possible that the model under consideration is no longer valid when you get near the outlier.
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.
What is a common term used to mean a measure of central tendency?
The answer is outlier
Is 101 a outlier?
No. A single observation can never be an outlier.
How does the outlier affect the median?
Outlier does not affect the median.
What would happen if a outlier was removed from the mean?
The answer depends on the nature of the outlier. Removing a very small outlier will increase the mean while removing a large outlier will reduce the mean.
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.
What is the outlier of 558286 94 96 99?

What is an example of a outlier range?
1,2,3,4,20 20 is the outlier range
