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.
This is where it can all go downhill quickly.  In the pressure to make as many pennies out of a nickel, a lot of research corporations will not just sell your answers but the data associated with it.  Details that you provide when taking paid surveys such as your name, address, age range can all be attached together quickly to fulfill a lot of larger companies' requests for information (RFI).

Send Earnings may have to be satisfied with the twentieth and final spot in our table, but that’s still an achievement to be proud of in such a competitive market. There’s a good selection of surveys to choose from, which I always welcome, and you can grab your money and run once you hit the thirty dollar threshold. There are lots of other money earning options as well, but watch out for the ‘play games’ pitfall as it could end up costing you more than you actually earn.

Ipsos are a globally respected name when it comes to opinion polls and market research, and by taking part in their surveys you can help them gain the vital information that helps them make business, consumer and political predictions. Unlike many of the other sites to feature in our Survey Cool 2018 top twenty it focuses solely and purely on offering surveys. It also means you won’t be distracted by video watching and game playing that typically pays a lot less. Here is a detailed review of Ipsos I-Say.
There’s a decent rate of surveys pinged your way as you can expect two or three emails a day inviting you to fill in particular questionnaires. In addition to this, there are freely offered surveys on their cleanly designed website each day which you can look through and decide if they take your fancy. Surveys on CashCrate are often outsourced to third parties though, so you can make more money on the survey side from other websites. Similarly they are known for passing your information on to other people, so to avoid the irritations of endless spam, make sure you set up a dedicated email address for your CashCrate account.
Rewards are paid out in cash and PayPal, but the catch of having short surveys is reflected in the pay, which can be miniscule per survey. As you need to earn $50 before you can withdraw anything, that’s a lot of low-paying surveys before you’ve made your money! Some people have complained online that once you get close to the withdrawal amount, the surveys dry up. One way around this is to refer a friend as you’ll receive a bonus when they sign up and you’ll hit your target to withdraw your funds. It’s a bit of a downside, but there are hundreds of very happy consumers who love the site, so it’s worth a shot, especially if you get fed up with the boring or repetitive nature of some of the quizzes elsewhere.
Like many survey sites, Toluna rewards you with points, which you can then cash out for vouchers for the usual suspects like Amazon and iTunes, or money through PayPal. A slightly novel element of the site’s payment plan is to offer the chance to take your points out early if you gamble them for prizes. While you have to store up a grand total of 60,000 points before you can claim vouchers for around $12 – something some people find to be a downside of the site – if you are willing to settle for a prize, you can play with just 500 points. You can decide to try your luck with a “giftie”, a kind of scratch card game. By gambling some points, you can see if you have won the gift or lost your points – so it is not one for the faint hearted!
*Member must "Activate" the Bonus in the Swag Ups section of your account. Bonus value is earned in the form of points, called SB. Get a 1000 SB bonus, which is equivalent to $10 in value, when you spend at least $25 at a store featured in Swagbucks.com/Shop. You must receive a minimum of 25 SB for this purchase, which you must complete within 30 days of registration. MyGiftCardsPlus.com and travel purchases do not qualify.
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.

Free to join, the site runs a range of special offers, including awarding prizes at random, giving you daily targets to hit for which you receive bonus points, and posting deals on their social media feeds. They have a great new app and a strong referral scheme. However, like everything, it’s not perfect – it can start to suck up a lot of your time. Swagbucks runs on the premise of incentivising day to day internet use to make both you and them money, so it is worth being aware of this so it doesn’t end up seeping into too much of your life!


i-Say. This site only provides surveys through Ipsos, the market research firm that owns it. The site offers fewer surveys than aggregators do, but you stay on i-Say for every survey, which makes the overall experience easier. Sometimes it displays surveys you already tried, which is confusing. You can cash out rewards starting at 500 points, which is equivalent to $5. For more information, check out the i-Say review.
To take surveys, you need to qualify. This means answering a battery of questions up front—before the paid portion of the survey. Page attempted a variety of side hustles to pay off her debt, and says that taking online surveys was the “least helpful” side hustle she tried, mostly because she simply couldn’t even get to the surveys themselves. “You can spend almost 10 minutes just trying to qualify for a survey, and then [get] declined,” she says. “It takes way too long to determine if you’re eligible to take the survey, just to make $5,” she says. Short of magically being the right demographic for every survey, you’re looking at getting turned away more often than not, and wasting time answering questions that don’t come with a pay off.
Joining isn’t as straightforward as merely signing up, because you need an invite. However it’s not as tough as it sounds, as there are plenty of links doing the rounds online if you look hard enough, and Pinecone also advertises on websites, so you might get lucky by keeping an eye on banner adverts. Once you’ve signed up, you’ll be vetted to see if you qualify – based on whatever demographics their clients want at that point – and if so, the fun begins!

While surveys vary widely in how they are conducted and used, there are a number of components that are common across nearly all surveys. Many of these common features have been studied in extensive detail by survey methodologists, psychologists, statisticians, and many other fields of research. The general process of survey research is outlined in the figure below.
