To find the limits of outliers in box and whisker plots, you first must determine the Interquartile Range. The Interquartile Range is the difference between the Upper Quartile and the Lower Quartile. For instance, if my Upper Quartile = 87 and my Lower Quartile is 52, then 87 - 52= 35. 35 is the Interquartile Range (IQR).
Next, you use the formula 1.5 x IQR to determine if you have any outliers.
Example:
1.5 x 35 = 52.5
Now determine the limit for the Upper Quartile by adding 52.5 to the Upper Quartile.
Example:
52.5 + 87 = 139.5
139.5 is the limit for the Upper Quartile.
Next, determine the limit for the Lower Quartile by subtracting the Lower Quartile from 52.5
Example
52 - 52.5 = -0.5
-0.5 is the limit for the Lower Quartile
Thus, the LIMITS are -0.5 and 139.5. In order for a number to be considered an outlier, it must either be less than -0.5 or greater than 139.5

How do you find clusters on a box and whisker plot?
You cannot, unless they are all outliers, and the plot records outliers separately.
What does the whisker in a box-and-whisker plot represent?
The whiskers mark the ends of the range of figures - they are the furthest outliers. * * * * * No. Outliers are not part of a box and whiskers plot. The whiskers mark the ends of the minimum and maximum observations EXCLUDING outliers. Outliers, if any, are marked with an X.
How do you find the minimum value of a box and whisker plot?
It i the smallest value in the data set and corresponds to the value of the left-most end of the whisker. Unless there were outliers, in which case it will be an "X" to the left of the left-whisker.
How do you find the minimum and maximum in a box and whisker plot?
Assuming no outliers, the two are the lowest (left-most) and the highest (right-most) values of the whiskers (not wiskers).
What is the upper extreme to a box- and- whisker plot?
THe maximum observed (excluding any outliers).

Do outliers count when calculating the range of a box and whisker plot?
no max-min

What do box and whisker plots tell you about data that measures of central tenancy do not?
The box and whisker plot informs you of the 5 number summary, which comprises of the minimum and maximum, the median, and the first and third quartiles. The minumum and maximum give you the range, which is not given by measures of central tendancy. also, if it a modified box and whisker plot, outliers will be marked separatley from the rest of the plot, outliers are also not included in the measures of center.
How are outliers of a data set related to the whiskers of its box plot?
Outliers on a modified box plot will be noted away from the ends of the whiskers, as they are not considered part of the range, due to the fact that they are so different from the rest of the data. In a regular box plot, the lowest value, whether it is an outlier or not, will be the beginning of the 1st whisker, the highest value, whether an outlier or not will be the end of the 2nd whisker.
How do you find the mode in a box and whisker?
You cannot. The mode is not part of a box and whisker plot.
Can you find the mean median mode and range on a box and whisker plot?
A box and whisker plot cannot identify the mean or mode.
What is an example for a box and whisker plot?
the example for the box and whisker plot is THESE NUTSS
What is the range of the data set in the box and whisker plot?
The whiskers go from the minimum to the maximum though outliers may be excluded. The box, itself, goes from the lower quartile to the upper quartile.
