What Is a Pictogram in Math?

In math, a pictogram or pictograph is the use of pictures or images to present data. To make a pictogram, a table of data is constructed with an accompanying key. An example of a pictograph is one that shows how many apples are eaten by student for lunch during a 5-day week.

On this type of graph, the data is recorded by placing apple images next to a specific day of the week. On the pictogram, the key may be that one apple represents 20 apples eaten and half an apple stands for 10 apples. A drawback of using this type of graph to record data is that it is not very accurate because it does not allow for showing frequencies of all possible data. Besides pictograms, some other ways to represent data are to use a scatter diagram or pie chart.
