How many outliers can a data set have?
There is no agreed definition of an outlier and consequently, there is no simple answer to the question. The number of outliers will depend on the criterion used to identify them. If you have observations from a normal distribution, you should expect around 1 in 22 observations to be more than 2 standard deviations from the mean, and about 1 in 370 more than 3 sd away. You will have more outliers if the distribution is non-normal - particularly if it is skewed.
Can you have more then one outlier?
Yes. If you have a large group that is very similar and 2 or 3 that are not similar, the numbers that are not the same are all outliers
Data that is more than 1.5 times the interquartile range from the quartiles?
Outliers
How can you use a z score to determine outliers?
Best to use a histogram i think! z scores can probably be used too however they seem more a method of how to transform outliers in workable scores.
How do outliers affect measures of center?
Outliers can significantly skew measures of center, such as the mean, by pulling the average in their direction, which may not represent the overall data well. For instance, a single extremely high or low value can distort the mean, making it less reflective of the typical values in the dataset. In contrast, the median is more robust against outliers, as it focuses on the middle value, thus providing a more accurate measure of central tendency in such cases. Overall, the presence of outliers necessitates careful consideration when interpreting measures of center.
Can there be 2 outliers in a set of data?
There is no limit to the number of outliers there can be in a set of data.
What are the limits on outliers?
there are no limits to outliers there are no limits to outliers

Can there be more than one outlier?
Of course. In a large sampling of data, a relatively small group of outliers is possible.
Can you have more than one outlier?
It depends on how many points you have, if you have 6 or 7 then only one outlier is really possible but if you have done 20 points the 2 outliers could be acceptable, but should still be avoided.
Can you have more then one outlier?
Yes. If you have a large group that is very similar and 2 or 3 that are not similar, the numbers that are not the same are all outliers
What do you call the numbers that cannot be arranged in to 2-row arrays?
Outliers.
Data that is more than 1.5 times the interquartile range from the quartiles?
Outliers
What is the ISBN of Outliers book?
The ISBN of Outliers - book - is 9780316017923.
Why is the interquartile range a more appropriate measure for spread than the range?
the interquartile range is not sensitive to outliers.
How many pages does Outliers - book - have?
"Outliers" by Malcolm Gladwell has approximately 320 pages in its paperback edition.
In general the median of a data set is more resistant to outliers than the mean.?
Yes, it is.
