More than one choice may be appropriate. A property management company would like to investigate the distribution of rental rates for 3-bedroom single family homes in the city. A representative of the management company selects a SRS of 175 3-bedroom single family homes and records their monthly rental rates.
Rental rate is a quantitative continuous variable.
Since the company would like to investigate the distribution of this variable a histogram or a boxplot would be the graphic to use. The same management company would like to compare rental rates for 3-bedroom single family homes in the north part and the south parts of the city. For comparing groups whose response is quantitative, a multiple boxplot can be used. Here we have a comparison of groups on a quantitative variable as well as some interest in changes over time. Hence, we ll use a multiple time series plot as the graphics display.
