What is the term for an exceptional value that can dramatically affect the mean?
That would be outlier.
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.
What is the Outlier of data?
An outlier is a value that is way too small or way too large compared to other observations. There is no formal definition of what "way too" is.
Explain the difference between the range and the outlier?
Range is the largest minus the smallest value in the data set. An outlier is a value that is far away from the majority of the data.
Is an outlier always min or max value?
Not necessarily.
