Generally a survey is a collection of information from a smaller group of people who represent a larger group. For example, a national survey would be a collection of data from a sample of the population and not everyone living in a country.
The results obtained form there would be seen to represent everyone.
Now, online surveys are founded on the same concept but like the traditional surveys they come in different forms or types. The types of surveys you will be offered will vary with survey websites.
This article will attempt to give a clear explanation of the different survey types you can take online.
Note that not all of these surveys can be done just by filling in a form on your computer. Some require you to actually undertake some activity before coming back to fill the form.
Focus group survey
Focus groups are basically based on a group of people sitting around a table and discussing a common subject. Focus groups have a moderator that controls the flow of the conversation to ensure that the required information is collected. Usually the moderator will start with general questions so to get everyone involved and relaxed.
This can also happen online, where the online survey company interviews people in a forum. This form of paid survey does not need any filling of a form but just to make your comments during the discussing. Generally you get paid for the amount of time spent taking part in the paid online focus group.
Online Panel group survey
This is another form of online paid survey where you are asked to fill in a questionnaire and then to send it back to the online paid survey company. This form is normally sent to your email inbox or you may receive a message asking you to log into the survey company's member page to take the survey. Either way, it is important to answer all paid surveys that are sent to you to ensure that the companies keep sending you more and more - consequently providing you with an even better chance to make more money from paid surveys.
Mystery shopper survey

In this form of paid surveys, the survey taker is required to go to any shop, restaurant, office etc. and buy or ask for the relevant product. Sometimes the online paid survey company can keep you informed about the survey details but most often may not to avoid having biased results.
Once you have done the paid survey you would then have to fill in a form to answer. This is the main part that result to your pay out, so if you don't fill the form in the right way then you may be paid for the survey at hand but may never be asked to fill in anther one again.
