DIFFERENT TYPES OF GRAPHS

Column graph Column graphs have a series of vertical blocks. Column graphs can be distinguished from histograms because the blocks always have gaps between them while histograms have no gaps.Use of column graphsA column graph is used to show relationships between groups. The two items being compared do not need to affect each other. It is a fast way to show big differences. Column graphs are an excellent way to show results that are one time, that aren't continuous - especially samplings such as surveys.

How to construct a column graph.1-Draw two axes: one vertical and one horizontal. Make sure you leave room at the edge of the page for your labels.2- Always place numbers on the vertical axis. Non-numerical groups are on the horizontal axis3- Label each axis 3- Columns should be of the same width and should not touch at all.4- Leave half of the column width at the start.5 - The scale should go up evenly and cover the largest and smallest values.6- Include scientific units where appropriate.7- Include a title to explain what the graph is about. Your title should start with: Graph of……..

Column graph

A column graph is used to show

relationships between groups.

Column graphs are an excellent way to show

results that aren't continuous - especially

samplings such as surveys.

A column graph has two lines or axes.

One is the horizontal axis which goes from side

to side.

The other is the vertical axis which goes up and

down.

Summary

Things you should follow when drawing a column graph

use graph paper

Draw in the two axes with a ruler

use a pencil

Column graphs have a series of vertical blocks.

Columns should be of the same width and should not touch at all.

Non-numerical groups are on the horizontal axis.

Always place numbers on the vertical axis.

Leave half of the column width at the start

Be consist-ent with the gap between the columns.

This should be half of the column width

The spacing between the columns is the same

The width of each column is the same
