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 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).
How do you Create a box plot of data that does not have any outliers?
Go into your data to determine which values are outliers and if they're significant and random (not an apparent group), eliminate them. This will take them out of your boxplot.
What is the upper extreme to a box- and- whisker plot?
THe maximum observed (excluding any outliers).
How do you find clusters on a box and whisker plot?

Why do you multiply by 1.5 in a box and whiskers plot?
When John Turkey was inventing the box-and-whisker plot in 1977 to display these values, he picked 1.5*IQR (inter-quartile range) as the demarcation line for outliers. This has worked so well, so we've continued using that value ever since.

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

Why do they invented the stem and the leaf plot?
to organize your data set and figure out mean, median, mode, range, and outliers.
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.
In a data plot about half the data points will lie below the line that best fits?
Yes. The exception arises when you have outliers.
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.
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.
