Question

Distinguish between:
Bar Diagram and Pie-Diagram

Answer 1

Pie Chart

A pie chart consists of a circle that collectively represents the entire group of what is being measured. Each specific statistic is represented by a slice, or sector, of the pie chart. The different slices are represented using different colors, and viewers can compare a large amount of individual stats at one time. Because viewers can understand pie charts at a glance, such presentation tools are often used as teaching aids for children.

Bar Chart

A bar chart, or bar graph, uses a graphing layout with bars laid out on the x-axis, which extend upward to be charted along the y-axis. Each bar represents a data segment being graphed, and the y-axis usually represents quantities or other values that can apply to each segment. Horizontal bar graphs are another type of bar chart, in which the axes are switched so that the y-axis contains the primary data segments and the x-axis monitors quantities or other values.
