Which type of graph do you think is best for showing Flores del Mundo’s membership trends over the course of the year?
I would choose a line graph for this purpose. Since we are interested in trends, I would choose a line graph without dots.
Does your answer change if you’re graphing total membership versus employee/spouse/dependent?
Yes, a stacked graph could be used for this purpose. This way you could show the trend while showing employee/spouse/dependent membership.
Does your answer change if you want to show Eastern and Northern on the same graph?
For this I would again suggest using a line graph if what you wantes to show was the membership trend. If we were to show total membership versus employee/spouse/dependent for Eastern and Northern, the I would use side by side stacked bars.
