Census: it is a survey that surveys the whole population or group. Horizontal axis: this is a line running across the graph. It has a label beneath it. Vertical axis: this is a line running up the side of a graph. It has a label next to it. Scale: The scales on horizontal or vertical axes are similar to the scales found on many measuring instruments. A scale is a series of numbers that are increasing or decreasing by the same amount. Part of the skill of interpreting a graph is reading the scales on the axes. Each scale will be labelled with the unit of measurement that has been used. What is a survey? Helps to find the views of the whole community or group Surveys are a primary source of information Uses questions Survey

because the blocks always have gaps between them while histograms have no gaps. 30 25 20 15 10 5 0 Pu Ye Red G Use of column graphs A column graph is used to show relationships between groups. Column graphs are an excellent way to show results that are one time, that aren't continuous - especially samplings such as surveys.

Origin of the words graph and data 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 axis 3- 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.. Things you should follow when drawing a column graph use grid paper Column graphs have a series of vertical blocks.

Leave half of the column width at the start Always place numbers (numerical groups)on the vertical axis. Columns should be of the same width and should not touch at all. use a pencil Draw in the two axes with a ruler Non-numerical groups are on the horizontal

Non-numerical group on the horizontal axis. Step 3: Label the axis Number of parents Step 4: Setting up the scales. Count how may squares represent 1 on vertical axis. On the horizontal axis, Leave 0.5 gap for the start (1 square) (half of the column width)
