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

3
Survey Use of surveys Real world application To find out the attitudes of people about various issues To measure client satisfaction

4
You need a quick and efficient way of getting information. You need to reach a large num ber of peopl e. You need statistically valid information about a large number of people. The information you need isn't readily available through other means. When should you conduct a survey?

5
How to conduct a survey 5- Graph your results 4- Choose a suitable graph 3- Record your results in a table 2- Ask people your question 1- Think of a question How to conduct a survey,,,. Type of sport Basket ball VolleyballSocce r Netball Number of students 7592

Types of graphs Line graphs Sector graphs Picture graphs Bar graphs Step graphs Column graphs 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 graphs A 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 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……..

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

13
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

This table shows the favourite sport played by year 7B. Types of transport Walk Train Dropped off by parents Bus Number of students 8591 Draw a suitable graph for your data. How year 7 get to school

16
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.

18
Types of Transport Number of students Method of transport by 7B The width of each column is the same The spacing between the columns is the same Non- numerical groups are placed on the horizontal axis. Numbers are placed on the vertical axis Title Leave half of the column width at the start.

19
Step 1: Draw the axes Step 2: Always place numbers on the vertical axis. Non-numerical group on the horizontal axis. Number of students Step 3: Label them 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).. Step 5: Putting up the values and drawing the columns Step 6: Add a title 0 Method of transport by 7B Title Types of Transport 1 cm Walk Train Dropped o ff Bus 1 2 3 4 5 6

20
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. Vocab page
