Solution:
A bar graph or Double bar graph would be most suitable representation to compare the median number of teeth for mammals and reptiles.
Keep in mind: Median of a data set is mid value , if arranged in ascending or descending order.
Step-by-step explanation:
Suppose a group of mammals,according to their weight is considered for study and their teeth are counted and median number of teeth of data set are calculated.
Similarly, for a group of reptiles which underwent for study for their number of teeth, and then median value of all reptiles which possess teeth is calculated.
So, best way to compare their number of teeth of mammals and reptiles is Draw the bar graph of each data set of mammals, and then also draw the bar graph of each reptile and then calculate the median value of mammal and reptile and then you can draw the graph separately for median values of both and then compare.
You can compare the medians of the two data set of Reptiles and Mammals by Double bar graph also.
