      • Which type of graph do you think is best for showing Flores del Mundo’s membership trends over the course of the year?

      • Does your answer change if you’re graphing total membership versus employee/spouse/dependent?

      • Does your answer change if you want to show Eastern and Northern on the same graph?

      I think a line graph would be best for showing Flores del Mundo’s membership trends over the course of the year, since line graphs effectively display changes over time. If I was graphing total membership versus employee/spouse/dependent, I would use a bar graph instead of a line graph, because this is a part-to-whole relationship, which measures individual categorical subdivisions as ratios to the whole. I would use a line graph to show Eastern and Northern membership trends over the course of a year on the same graph, because the same time series is being used, and I am specifically still interested in seeing the membership trend for each region and trends are most effectively displayed in line graphs.

      To demonstrate the Flores del Mundo membership trends over the course of the year, I would use a line graph to show the overall trend. The reader would be able to get a clear sense of how the data has changed through time. If the total membership was split into two datasets to look at the Eastern and Northern membership over the course of a year, I would still use a line graph to clearly summarize the membership trend and to allow for easy comparison between the two regions.

      To graph the total membership vs. employee/spouse/dependent, I would chose a bar graph. When re-reading ‘The Right Graph’ article, the author shows an example of two sets of categorical data which could be used to easily display the total membership in addition to a bar for each subgroup (employee, spouse, or dependent). I would suggest dividing the time into quarters as the author did to ensure the graph is easy to read with the multiple bars at each timepoint.

      If Flores del Mundo wanted to track membership rates over the course of a year, I would recommend using a line graph. Line graphs easily allow the user to look for trends over time in a visually appealing manner. In addition, if the data were split between Northern and Eastern regions, I would suggest using a line graph with a line for each region. A bar graph could also be used, but it may be visually easier to compare membership rates between regions with the line graph.

      If graphing membership based on category (employee/spouse/dependent), a bar graph would be useful. Because the data captures an entire year, it may be helpful to stack the bars rather than place them side-by-side for each month. This method allows the user to examine categorical data as a part of a whole and is more visually appealing.
