Astudent analyzes soil samples from her backyard. she organizes the samples into three categories, based on their ph. the three categories are: ph less than 8, ph between 8 and 8.5, ph greater than 8.5. which type of graph should she use to show the percent of samples in each group?
stem and leaf plot
circle graph
line graph
scatter plot

The correct answer is circle graph.

Explanation:

The pie chart is also known as a circle graph has the best application in observing the relative size of different sectors. The entire circle being 100 percent, each sector will demonstrate the percent of every category. In the given question, the circle will be differentiated into three different sectors, in which the size is equivalent to the percent of each one.  

There are three categories: pH less than 8, pH in between 8 and 8.5, and pH more than 8.5. The entire circle is 100 percent, that is, the sum of the three categories would be 100 percent.
