Tableau - Box Plot

2. The box plots are also known as a box-and-
whisker plots.
They show the distribution of values along an axis.
Boxes indicate the middle 50 percent of the data
which is, the middle two quartiles of the data's
distribution.
The remaining 50 percent of data on both sides is
represented by lines also called whiskers, to
display all points within 1.5 times the interquartile
range.
which is all points within 1.5 times the width of
the adjoining box, or all points at the maximum
extent of the data.

3. The Box Plots take one or more measures with
zero or more dimensions.
Box plots divide the data into sections that each
contain approximately 25% of the data in that set.
Box plots are useful as they provide a visual
summary of the data enabling researchers to
quickly identify mean values, the dispersion of the
data set, and signs of skewness.
A boxplot can give you information regarding the
shape, variability, and center (or median) of a
statistical data set.
Also known as a box and whisker chart, boxplots
are particularly useful for displaying skewed data.
Statistical data also can be displayed with other
charts and graphs.

4. Bullet graphs are used to compare one value,
represented by a horizontal bar, to another value,
represented by a vertical line, and relate those to
qualitative ranges.
It compares sales performance for spices in
different regions this year to sales performance
last year.
The bullet graph features a single, primary
measure (for example, current year-to-date
revenue), compares that measure to one or more
other measures to enrich its meaning
(for example, compared to a target), and displays
it in the context of qualitative ranges of
performance, such as poor, satisfactory, and good.
Uses of Bullet Graph

5. Creating a Box Plot
Using the Sample-superstore, plan to find the size
of profits for the respective category for each Ship
mode values.
To achieve this objective, following are the steps.
Step 1 − Drag and drop the dimension category
to the Columns shelf and profit to the Rows
shelf. Also drag the dimension Ship mode to
the right of Category in Columns shelf.
Step 2 − Choose Box-and-Whisker plot from
Show Me. The following chart appears which
shows the box plots. Here, Tableau
automatically reassigns the ship mode to the
Marks card.

7. Box Plot with Two Dimensions
You can create box plots with two dimensions by
adding another dimension to the Column shelf.
In the above chart, add the region dimension to
the Column shelf.
This produces a chart which shows the box plots
for each region.
