What is an outlier on a stem and leaf plot?
An outlier is an extreme point of data on the plot. It is significantly greater or less than the rest of the data. Example: *50% of the class got 80/100 points on the test *49% of the class got 78/100 points on the test. *However, only 1% of the class got 99/100 points on the test. The small percentage that got the 99 would be the extreme 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.
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 an example of a outlier range?
1,2,3,4,20 20 is the outlier range
