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.
Return on Time: 3.5/5.0- Their payrate isn’t overwhelming- the average per hour hovers around $3. Depending on the user’s activity on the website, it can take anywhere from a couple of days to as long as a month just to earn CashCrate’s cash-out amount of $20. You certainly won’t be making top-dollar with this site, but despite their low pay they do pay their members consistently.

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).


The free site screens you when you sign up, asking a range of questions so you can be sent the surveys which will be suitable for you. You can also join up with a social media account like Facebook or LinkedIn instead of using your email address. Filling out surveys for money with Opinion Outpost will first give you Opinion Points – with 10 points worth $1. Most surveys will take between 10 and 30 minutes and are worth anything from $1 to $5. Typical survey time is around 15 minutes, and participants are also entered into quarterly prize draws, touted to be for $10,000! However some people think their surveys don’t come around often enough, and completing some surveys will enter you into prize draws rather than paying out cash.

One of the most popular sites, and rightfully so, Swagbucks offers traditional surveys as well as a range of additional ways to make cash. Filling out surveys for money will reward you with points called Swagbucks which can be cashed out through PayPal, or redeemed as gift cards for shops including Amazon.com. As a sweetener, they’ll even give you $5 just for signing up.

While it might be hard to believe at first, American Consumer Opinion will pay you real, actual money to share your opinions and complete online surveys. Once you join their online opinion panel, you’ll be asked to offer opinions on new products you have tried, test out new advertising campaigns, and tell companies what you think of their marketing techniques and slogans.

This site pays highly – at least $3 a survey and up to $6 for testing products. If you stay with them, the pay even increases by a few dollars, taking the wage far above the standard survey rate. Owned by the renowned New York market research company Nielson, Pinecone offers a variety of content and emails surveys to members as and when they are suited to you.
After you sign up, you’ll receive surveys on various topics and products via email. Once you complete these surveys and build up a stash of points, you can redeem them for cash via PayPal, purchases made through Amazon.com, or gift cards to various retailers. As an alternate suggestion, you can even redeem your rewards as a donation to the Red Cross.
I’ve had bad experiences with iPoll. I’ll answer the “screening” questions and am told I qualify to take the survey, then once the survey is around 90% complete, I’m told the survey is “closed”. My guess is this is how they’re getting their data without having to pay participants. I’ve also gotten “invalid website” in the middle of some of their surveys as well, of course, after answering 15 minutes of questions.

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!

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.
There have been some reports of technical glitches on the site preventing users from receiving their earnings, but customers services are contactable and said to clear up most issues for workers. Valued Opinions has a unique “badge” program, allowing its most active members to work up five levels of achievement from bronze through silver, gold and platinum to the top tier of diamond, by carrying out extra mini tasks.
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.
