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.
What is unaffected by outliers?
interquartile range
Why is the interquartile range a more appropriate measure for spread than the range?
the interquartile range is not sensitive to outliers.
What is the primary disadvantage of using the range to compare the variability of data sets?
The range is very sensitive to outliers. Indeed if there are outliers then the range will be unrelated to any other elements of the sample.
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.

Which graph type would be best suited for calculating the interquartile range for vehicle prices on a certain car lot?
Box & Whisker
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.
What is unaffected by outliers?

Why is the interquartile range a more appropriate measure for spread than the range?
the interquartile range is not sensitive to outliers.

What is the Formula for least count of voltmeter?
The formula for calculating the least count of a voltmeter is least count = Range / Number of divisions. Where the Range is the maximum voltage that the voltmeter can measure and the Number of divisions is the total number of divisions on the voltmeter scale.
What conclusions can you draw from comparing two sets of related data displayed in box and whisker plots?
You can determine differences in:the median, a measure of central tendency;the inter quartile range (IQR). This is a measure of the spread of data around the median;skewness;number of outliers.
A box plot is also known as a box-and-whisker plot.?
A box plot is a visual representation of the distribution of a dataset. It displays the minimum, first quartile, median, third quartile, and maximum values of the dataset. The "box" in the plot represents the interquartile range, while the "whiskers" represent the range of the data excluding outliers.
What is the IQ range?
If you are talking about statisitics, in a box and whisker graph it is the interquartile range.
