Question

a two - way table describes the relationship between two categorical variables whose values are depicted as headings of each row and column. the numbers in the table can depict the count of individuals who exhibit both values of the variable or they can depict the percentages of the row total, column total (shown above), or table total.
segmented / stacked bar graph
a segmented bar graph is another variation of a bar graph that shows the relationship between two categorical variables. it more clearly shows the proportion of observations for the values of one variable.
compare and contrast side - by - side bar graphs and segmented bar graphs:
give one advantage to using a segmented bar graph
two numbers are circled in the table. what does each represent? 16 is the number children with contacts, 54.7% of adults with no eye wear

Explanation:

16 is count of children with contacts. 54.7% is % of adults with no eye - wear. Segmented bar graph shows proportion better than side - by - side. Advantage: clearly shows part - to - whole relationships.

Answer:

16 represents the number of children with contacts. 54.7% represents the percentage of adults with no eye - wear.
One advantage of using a segmented bar graph: It clearly shows part - to - whole relationships.
