Name the three primary types of graphs often used in presentations. How are they similar? How are they different?

What will be an ideal response?

All graphs are helpful in showing differences over time, demonstrating how a whole is divided into parts, and comparing different amounts or sizes of things. They differ in their look, shape, and function. But all types should be simple, clear, and uncluttered. The three main types are: 1) the pie graph – demonstrates relative proportions, but is only useful when the total equals 100 percent; 2) the bar graph – shows at a glance a set of figures or changes in data over time; and 3) the line graph – illustrates shifts over time, and can compare relative changes across several groups.
