Answer #1

The histogram is like a column graph without the spaces between columns. The frequency polygon is a special line graph used in statistics. These graphs can be drawn separately or combined. The information in a frequency distribution table can be used to draw these graphs. By using histogram we can calculate the mode.

Frequency polygons are a graphical device for understanding the shapes of distributions. They serve the same purpose as histograms, but are especially helpful for comparing sets of data. Frequency polygons are also a good choice for displaying cumulative frequency distributions.
