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.
How do you do a box and whisker plot?
A box and whisker plot is used to show range, you must first find out the quartiles. The first quartile is the left edge of the box, the third quartile is the right edge of the box and the median is the line in the middle. The whiskers are the highest and lowest values in your data set. Sometimes if you have a value in your data that is a long way out then you may not use it as a whisker, this is an outlier.A boxplot is a way of depicting groups of numerical data. They have many lines extending vertically from the whiskers (boxes).
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.
Which type of graph is best for revealing measures of spread and central tendency of a data set?
box-and-whisker plot
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

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.
In a box-and-whisker plot what fraction of the data is greater than the first quartile?
57 is not right
A box and whisker plot has 4?
A box and whisker plot has four quartiles in which its data is spread across.

What word is used for data display that helps you to see the way data are distributed?
box- and - whisker plot
Which word best describes what you can observe about the data displayed by a box and whisker plot?
the data most likely
What are box and whisker diagrams used for?
Box and whisker plots are based on medians. The first step is to rewrite the data in order, from smallest length to largest. Then find the median of all numbers. The next step is to find the lower median... according to your data. Next, you find the upper median. Now you are ready to construct the actual box and whisker graph. First, draw an ordinary number line that extends far enough to include all of the numbers in your data. Then, locate the main median using a vertical line just above your number line. When you locate your lower and upper median, you place smaller vertical lines on top of those. Next, draw a box, using the lower and upper median lines as endpoints. Finally, the whiskers extend out to the data's smallest number and to the largest number. This is a box and whisker plot.A box and whisker plot is used to display a set of data so that you can easily see where most of the numbers are.Here is an example and a picture of a box and whisker plot!By: a 7th grade Algebra 1 student
How do you use a box and whisker plot?
Box and whisker plots are used to give a visual indication of where quartiles and highest/lowest values fall, so they're useful for visually comparing various sets of data. The "whisker" on the left extends to the lowest value in the data range (the left-most point). The first edge of the "box" indicates the lower quartile, the middle line in the box represents the median quartile, and the upper edge of the box represents the 3rd quartile. The "whisker" on the right extends to the highest value in the data set. Clearly when using many box and whisker plots, and comparing them to each other, it helps greatly if you use the same scale on each plot. Sometimes it may be decided that your lowest/highest data values are "outliers" (anomalous results), in which case they are still included in the box and whisker plot, but they should be demarcated by a hollow circle wherever the outlier is deemed to be.
What type of graph is best suited for graphing the quartiles of a set of data?
A Box and Whisker Plot
What are the advantages of box and whisker plots?
It's eaiser to see the outlier ( odd number) out of the data.
