How to Do a Survey

Survey Says ...

Turn on the television, radio or open a newspaper and you will often see the results from a survey. 

• Gathering information is an important way to help people make decisions about topics of interest. 
• Surveys can help decide what needs changing, where money should be spent, what products to buy, what problems there might be, or lots of other questions you may have at any time. 
• The best part about surveys is that they can be used to answer any question about any topic.

You can survey people (through questionnaires, opinion polls, etc) or things (like pollution levels in a river, or traffic flow).

Four Steps

Here are four steps to a successful survey:

• Step one: create the questions
• Step two: ask the questions
• Step three: tally the results
• Step four: present the results

Let us look at those steps in more detail ...

Step One: Create the Questions

The first thing is to decide is

What questions do you want answered? 

Sometimes these may be simple questions like: 

• "What is your favorite color?" 

Other times the questions may be quite complex such as: 

• "Which roads have the worst traffic conditions?"

Simple Surveys

When doing a simple survey, you can use tally marks to show each person’s answer:

Sometimes, it is helpful to be creative in how the people can respond.  It makes it more fun for both you and your respondents (the people answering the question). 

Step Two: Asking The Questions

Now you have your questions, go out and ask them! But who to ask?

When you are sampling you should be careful who you ask.

To be a good sample, each person should be chosen randomly

And the surveys where people are asked to respond are not very accurate, because only certain types of people take the time to answer.

So be careful not to bias your survey. Try to choose randomly.

If you choose a person and they do not want to answer, record "no answer" on the survey form and mention how many people did not answer in your report.

After completing a sampling survey you can use the information to make a prediction as to how the rest of the population might respond.

Your results are better when you ask more people.

Step Three: Tally the Results

Now you have finished asking questions it is time to tally the results.

By "tally" I mean add up. This usually involves lots of paperwork and computer work (spreadsheets are useful!)

Step Four: Presenting the Results

Now you have your results, you will want to show them to other people in the best possible way.

We have written a special page called Showing the Results of a Survey, but here is a quick summary:

Tables

Sometimes, you can simply report the information in a table. 

A table is a very simple way to show others the results.  A table should have a title, so those looking at it understand what results the table shows:

Statistics

You can also summarize the results using statistics, such as mean or standard deviation

Graphs

But nothing makes a report look better than a nice graph or chart.

Use Data Graphs (Bar, Line and Pie) to make them.

Have fun asking questions!
