Select a representative sample: Selecting a representative sample from your sampling frame is also important for collecting valid and reliable data about the population of interest. For example, if you are sampling from a large database of customer email addresses and only wanted one response per household, you might want to cross-check each email address against mailing addresses and remove duplicates to avoid some households having a greater probability of selection. Then you would likely draw a random sample from the remaining list of email addresses.
One of the great things about Survey Savvy is that they really do offer a great variety of surveys to choose from, so you won’t simply be talking about the consumer goods that you buy on a day to day basis. They have surveys on topical issues and about politics in general, but don’t worry you don’t have to be a political animal to be able to complete the survey – you just need to have an opinion. Another thing I really appreciated about survey savvy is that their surveys are short and snappy, and you can complete them within ten minutes or even less. That means you can quickly earn the points that can then be exchanged into folding cash.
And lastly, let's discuss privacy.  In some ways, Pinecone Research gets it right – they use the information to verify you are not a duplicate or in any way defrauding them out of a valuable opinion.  After that, they only use your personal information for developing metrics and usage statistics – not giving it out to every third party that comes along.  More importantly, they take consumer information privacy seriously.  When they compile their reports for their clients, they scrub all data of any identifying information.

The cost of living has continued to rise, while the average salary is still somewhat stagnant when compared to a decade ago, and this is why so many Americans have started to look for ways to earn money at home without having to invest too much time or effort. Family and friends come first, but with paid online surveys, you will not have to cut out any portion of your routine to earn extra money online, as you can instead go through the processes in your sparest of spare time. 

The number one reason why I liked MySurvey the best out of the 30-something sites I had the privilege or misfortune to try, was no doubt its versatility. This versatility is present not only in the reward system and the referral program – which are important aspects on their own – but clearly shows in their surveys too. Filling out boring surveys always feels like hard work, even though it’s really not if you think about it. With MySurvey, you will see a huge variety of different topics.
CashCrate. Many sites reward users through a confusing point system, so we appreciated that CashCrate discloses the monetary value of each survey. However, during surveys, we often struggled to determine when we were actually earning money and when we were attempting to qualify for paid opportunities. And after five hours in this confusing process, we didn’t earn enough money to cash out. Read more in our CashCrate review.
Survey Junkie. This site is a smaller survey aggregator, but it stands out. The site has a clean, easy-to-use dashboard and offers a high point value for each survey you complete. The point system is direct and shows you how much your points are worth in dollars right on the dashboard. But you have to get to 1,000 points, equal to $10, before you can cash out. Check out our Survey Junkie review for more information.

MySurvey. This site offers an easy-to-use dashboard, a steady stream of surveys and a decent qualification rate — 28.89%. However, we encountered numerous issues with the site, which made the survey-taking experience generally poor. The disqualification policy was unclear and the 1,000-point minimum cash-out requirement was hard to hit. Check out our MySurvey review to learn more.

By only sending you questionnaires you are already qualified for, Pinecone wastes far less of your time than many sites which require you to fill our qualifying questions before starting each survey. However some users have said they don’t receive very many surveys, which could be a consequence of their careful filtering. Equally the site retains the right to remove you from their panel if you no longer fit their desired demographic, so make the most of your membership while you have it!
Paid survey site companies invest billions of dollars into marketing research online.  They always want to find out more intricate details of a consumer's relationship with their product.  Whether it's a new television show or just an existing product line, companies like Disney, Samsung, and Sony go to great lengths to find out their ideal audiences.

Design and pre-test questionnaires: Designing the questionnaire carefully and then pre-testing it before fielding it to your entire sample is crucial to getting data that are valid and reliable. For example, careful questionnaire design and pre-testing can help reduce the chance that respondents may interpret the meaning of questions differently. Future posts in this series will tackle these important steps in much greater detail.
