An outlier can be very large or small. its usally 1.5 times the mean. they can be seen with a cat and whisker box

The answer to the question is YES.
"Its usually 1.5 times the mean" is utter rubbish - apart from the typo. If a distribution had a mean of zero, such as the standard Normal distribution, then almost every observation would be greater than 1.5 times the mean = 0 and so almost every observation would be an outlier!
No.
There is no universally agreed definition for an outlier but one contender is values that are more than 1.5 times the interquartile range away from the median.

How does the outlier effect the mean median and mode in a set of data?
There would be a difference to the median. The old number wouldn't be the median but the mode wouldn't change. If the outlier is a high value, it will cause the mean value to shift to the higher side, while a low valued outlier will drop the mean value to a lower number.
A data value that is much higher or lower than the other data in a set is called what?
it is called an outlier
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".
What do large values of a chi square statistic indicate?
A large value for the chi-squared statistic indicates that one should be suspiciuous of the null hypothesis, because the expected values and the observed values willdiffer by a large amount
What is 6 to the 1000th power?
6 to the 1000th power is an extremely large number. The value can be calculated by multiplying 6 by itself 1000 times, resulting in a number with 1502 digits. This number is so large that it is difficult to comprehend or visualize without the use of advanced mathematical tools.
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.
How does the outlier affect the median?
An outlier can significantly impact the median by pulling it towards the extreme value of the outlier, especially when the dataset is small. This can distort the central tendency measure that the median represents and provide a misleading representation of the typical value in the dataset.
An extreme value in a set is called what?
An outlier (mathematics/statistics), or radical value (sociology).
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.
How does an outlier effect the range?
An outlier will have a huge affect on the range as the range is the largest value minus the smallest value.
What is the term for an exceptional value that can dramatically affect the mean?
That would be outlier.
What is the effect of the a small outlier value Will it affect of a data set?
No. The data set will remain the data set: they are the observations that are recorded.
A value separated from the rest of the data?
outlier
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.
What is an extreme value within a data set?
Outlier
If we are moving from a large value to a small value we move the decimal point to the?
If we are moving from a large value to a small value we move the decimal point to the left.
