(a) I would observe the rent of all tenants in 4 areas and then compare the results.
(b) I would use the mean value to determine the average amount of rent in all areas. (c) The mean values are: Area A: μ=1005.5; Area B: μ=887.0; Area C: μ=881.0; Area D: μ=945.5.

(a) I would use the column chart because we are comparing continuous data.
(b)
Average Monthly Rent (c) It appears that the monthly rent in Area A is higher than the rents in other areas of the city. Tenants in Area A pay $118.50 more than tenants in Area B, $124.50 more than in Area C and $60.00 more than in Area D. This means that the tenants in Area A pay a significant amount more than the others.
