Survey
A way of collecting information
Helps to find the views of the whole community or group
Surveys are a primary source of information –provide link to the vocab page
What is a survey?
Uses questions
Survey
Use of surveys Real world application To find out the attitudes
of people about various issues
To measure client satisfaction
• You need a quick and efficient way of getting information.
• You need to reach a large number of people.
• You need statistically valid information about a large number of people.
• The information you need isn't readily available through other means.

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.

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
Title
The scale is going up by one
Numbers are placed on the vertical axis
Non-numerical groups are placed on the horizontal axis.

Step 4: Setting up the scales. Count how may squares represent 1 on vertical axis.
On the horizontal axis, Leave 0.5 for the start or half a column width.columns should be of the same width (1cm or more)..

Primary source of information: that is, you directly ask someone for a response to a question, rather than using any secondary sources like written records.Survey: a way of collecting information Column graph: Column graphs are an excellent way to show results that aren't continuous - especially samplings such as surveys.Conduct: organize and carry out.
