I don’t think I’ve used box-and-whisker plots much in the workplace, but I’ve used histograms to display experimental results. Most recently, I’ve used both to help determine whether or not data is normally distributed and whether or not there is equal variance in data sets for my biostatistics class.
I would choose a vertical bar graph. Curative Care visits are the most frequent in the Eastern and Northern zones. In the Eastern Zone, Inpatient Obstetrics and Inpatient Medical are the least frequent claim types. In the Northern Zone, Speech Therapy is the least frequent claim type.
I think a line graph would be best for all three so that you can easily see the trends from month to month.
Stephen Few defines a dashboard as “a visual display of the most important information needed to achieve one or more objectives; consolidated and arranged on a single screen so the information can be monitored at a glance.” The WHO local maternity dashboard in Figure 1 includes a table containing performance metrics related to maternal morbidity and mortality, with target percentages, followed by yearly totals and monthly trends. The monthly trends are color-coded into three groups by how close or far they are from the target percentage. The table displays the final calculations and provides updated snapshots of maternal health trends by visualizing the different color groups. It is possible to see quickly whether a country or hospital is trending towards meeting the target percentage for a particular maternal health metric or not, so the WHO local maternity dashboard meets the definition by Stephen Few.
