Descriptive Statistics: Textual & Graphical (pdf)

Bar Graph Example
• Next, the team draws a
bar graph using the data
they have collected so
they can visualize the
waiting time problem.
• Looking at the bar
graph, the team agrees
that waiting time for
registration is the
biggest problem. They
decide to look more
carefully into the
registration process to
better describe the
waiting time problem
that occurs during
registration.
