Statistics homework question answer, step 1, image 1

 

Step 2

a) The graphical chart that should be use to compare the number of individuals in each location group is bar graph.

The reason is that bar graph makes its easy to compare the number of individuals (frequency). 

The bar graph is given as:

Location Category Frequency
Location group A 5
Location group B 7
Location group C 12
Location group D 25
Location group E 10
Location group F 6

Statistics homework question answer, step 2, image 1
