A new model of shirt at the clothing store comes in 4 colors: black, white, red, and blue

The data provided of the 16 sold shirts can be used to count the frequency of each color.
The results are shown below:
White = 5
Black = 2
Blue = 4
Red = 5
We can check the total is 5 + 2 + 4 + 5 = 16
Now we are ready to draw the bar graph, where each color must have a height that equals its frequency.
