How do you compare data sets using box-and-whisker plots?
You can see which has the largest spread of data.... Where the extreme values lie... The bigger the box the wider the spread of half of the data... and vice versa
What are box-n-whisker plots used for?
A basic summary of data or a simple comparison of a few sets of data.A basic summary of data or a simple comparison of a few sets of data.A basic summary of data or a simple comparison of a few sets of data.A basic summary of data or a simple comparison of a few sets of data.
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.
Can two box plots have the same range and IQR and yet have completely different data?
No. Four of the data elements must be identical.
Why do you use box and whisker plots?
Because you can compare the values easily, for instance, you can compare the highest and lowest value and compare this to the mean, does the highest and lowest value differ greatly from the mean? Then you know the correlation is a bit unpredictable, you can also use this to compare two box plots, putting them together you can see through the median and quartile range the best way to do something, etc.

Could you give us the answers for pg 344 on world histor ags?
Compare the shape,center,and spread of the data in the box plots with the data for stores A and B in the two box plots in example 2.

How do you compare box plots?
by looking at it and seeing the difference
How do you create a parallel box-and- whisker plots?
Parallel box and whisker plots are regular box and whisker plots, but drawn "one-above-the other" on the piece of paper. To enable to do this easily, draw an x-axis which is big enough for the largest value in the data, and small enough for the smallest value in the data (in the entire collection of data). Plot each box-and-whisker diagram below each other.
What are the advantages of box and whisker plots?
It's eaiser to see the outlier ( odd number) out of the data.

What are questions of box and whisker plot?
What are the minimum, lower quartile, median, upper quartile and maximum?What the range and interquartile range are.whether the data ore positvely or negatively skewed.How two (or more) data sets compare in terms of the "average" and spread.
You want to construct a box-and-whisker plot from a data set What is the first thing you should do?
Box-and-whisker plots highlight central values in a set of data. In order to construct a box-and-whisker plot, the first step is to order your data numerically and find the median value.
What are box and whisker plots used in?
Also called the box plots, see: http://mathworld.wolfram.com/Box-and-WhiskerPlot.html Many other excellent references can be found on the internet. The intent is to visually show graphically the mean (or median) of the data and the variability of data in terms of first quartile (Q1) and third quartile (Q3). Typically, it is applicable when there is sufficient and related data for a particular interval of time and the variability (range) of this data is of interest. The focus in generally is a time trend in the data. Changes in stock market prices or other economic/ financial analyses can use box plots. An example can be the selling price of automobiles per month because perhaps the median price is going down, but the high priced cars (Q3) is going up.
