Identify and explain the four different types of graph. Provide examples of topics or information that might warrant the use of each

What will be an ideal response?

Answer: Examples will vary but answer should include the following:
1. A bar graph consists of flat areas—bars—whose various lengths represent information.
2. A pie graph shows the individual shares of a whole and are especially useful in helping listeners to see quickly how data are distributed in a given category or area.
3. Line graphs show relationships between two or more variables. Line graphs can organize statistical data to show overall trends, and can cover a greater span of time or numbers without looking cluttered or confusing. A simple line graph communicates better than a cluttered one.
4. Picture graphs look somewhat less formal and less intimidating than other kinds of graphs. One of the advantages of picture graphs is that they need few words or labels, which makes them easier for an audience to read.
