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 the whiskers of a box plot?
They are some measure of the dispersion or range of numbers in the set of data.
What numbers do you plot to make a box and whisker plot?
Here are some steps to make a box and whisker plot: 1. Sort your data set from smallest to lowest 2. Locate and draw the median (or middle value) 3. Identify the numbers forming the lower half of the data set, and draw the median of these numbers. 4. Identify the numbers forming the upper half of the data set, and draw the median of these numbers. 5. Now connect the medians to make the box 6. Lasty, plot the least and greatest values from the entire set and connect them to the box with a line This may sound complicated, but is actually very easy if you can visualize it. Here is a site with an animated lesson and an interactive activity that will draw a box plot for any data set you create. http://www.brainingcamp.com/resources/math/box-plots/box-plots-lesson.php
Which type of graph is best for revealing measures of spread and central tendency of a data set?
box-and-whisker plot
What is the first thing you need to do to create a box and whisker plot of a data set?
You need to do a cumulative frequency curve

How do you set up a box and whiskers plot with multiple numbers?
By transferring the numerical data from the cumulative frequency curve into a box and whiskers plot.
What is a representation of data that shows the extremes and quartiles of a data set?
Probably the box and whiskers plot, but there are others.
What are the whiskers of a box plot?

What type of graph is best suited for graphing the quartiles of a set of data?
A Box and Whisker Plot
When do you use a box-plot?
A box plot may be used at a preliminary stage to determine the centre and spread of a set of data. The box [and whiskers] plot measures the central point by the median and the range from the maximum and minimum or the quartile points.

What is the purpose in a box and whisker plot?
A box and whiskers plot is a very simple way off showing summary information for a set of data. This can allow some quick analyses of the location and spread of data and permit simple comparisons between sets of data.
What type of graph is best for revealing the upper and lower quartiles of a set of data?
box-and-whisker plot
What is the definition of box plot?
a graphic way to display the median, quartiles, and extremes of a data set on a number line to show the distribution of the data.
Which type of graph is best for revealing measures of spread and central tendency of a data set?
box-and-whisker plot
