Use the
Bar Chart Worksheet
to create a bar chart to compare values across multiple categories of data,
such as, before and after.
For example, you can compare defect rates, COPQs, or other
similar metrics for different levels of a process input.
The
Bar Chart Worksheet
answers the following questions.
Do changes to a discrete
process input have an effect on the process output?
If you make a change to the
process, are the effects on the process output the same, proportionally the
same, or different?
How-to
Your data must include summarized values of one variable. You can also
have an optional second categorical variable with two levels.
Note
If you have the data values, use other graphs. Plotting the data,
instead of the summarized values, provides more information about your data.
For more information, go to
Graph Your Data.
In the worksheet, enter a
label and a value for each categorical variable.
To compare a second 2-level
categorical variable, such as before/after, enter a comparison value and a
label for each bar cluster.
View the completed bar chart
and summarize the results.
