What is a data value that is quite separated from the rest of the data?

In statistics, the name for that is "outlier". Another possible word is "anomaly".


Is outcast and outlier called the same?

No.


If an outlier is included with a sample of 50 values all of which are the same what is the effect of the outlier on the mean?

By definition, an outlier will not have the same value as other data points in the dataset. So, the correct question is "What is the effect of an outlier on a dataset's mean." The answer is that the outlier moves the mean away from the value of the other 49 identical values. If the outlier is the "high tail" the mean is moved to a higher value. If the outlier is a "low tail" the mean is moved to a lower value.


Is Median an outlier?

No, median is not an outlier.


Can a outlier be zero?

Would a mean be smaller or larger if you leave out an outlier?

How does the outlier affect the median?

Outlier does not affect the median.


Is 101 a outlier?

No. A single observation can never be an outlier.


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.
