XIX.Bar Graphs

The owner of Sam’s Shirt Shop recorded daily sales of T-shirts for a week.
He then displayed the results in a bar graph. A bar graph is especially
useful for comparing numerical data.


A bar graph uses vertical bars or horizontal bars

of different lengths.

The length of each bar is proportional to the
number the bar represents. The scale on the
bar graph is divided into equal intervals.

The bar graph shows the same information as

the table. On which day was the least number
of T-shirts sold? On which day was the greatest
number of T-shirts sold? How does the bar graph
help you answer these questions?

The least number of T-shirts was sold on Wednesday.
The greatest number of T-shirts was sold on Friday.
The bar for Wednesday is the shortest bar.
The bar for Friday is the tallest bar.
