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.
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.
When should relative frequencies be used when comparing two data sets?
When comparing large data sets.
When would you choose a bar graph to present data?
when i am comparing data
Why bar graphs are useful for comparing data?
bar graphs are useful for comparing data b/c you cn actually see what the difference is between them.

A box and whisker plot has 4?
A box and whisker plot has four quartiles in which its data is spread across.
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 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.

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.
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 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 is the term for a visual representation of data?
The term for a visual representation of data is a data visualization.
When should relative frequencies be used when comparing two data sets?
When comparing large data sets.
Is diagram the visual representation of data in Excel?
A chart is a visual representation of data in Excel.
What is Visual display of data?
A visual display of data is called a chart, table or a graph.
