Many surveyors want to track changes over time in people’s attitudes, opinions and behaviors. To measure change, questions are asked at two or more points in time. A cross-sectional design, the most common one used in public opinion research, surveys different people in the same population at multiple points in time. A panel or longitudinal design, frequently used in other types of social research, surveys the same people over time. Pew Research Center launched its own random sample panel survey in 2014; for more, see the section on the American Trends Panel.

What It Is: Many companies pay online testers to make sure websites are intuitive and easy to navigate. "You basically follow the instructions you're given to check out the website," says Anna Thurman, founder of, a site that has reviewed more than 500 online work opportunities. "It usually only takes about 15 minutes per test." Thurman recommends registering with 10 to 12 different companies since the opportunities to test these sites are doled out first come, first served. "There are people who make $100 to $200 a month by staying on top of those tests," Thurman says.

MySurvey is actually and adaptation of a program that was started back in 1946. It began as the National Family Opinion organization that used to send out surveys through the mail. In 2001, they joined the digital age, and now they are one of the best survey sites around. According to the website, they have issued out more than $15,000,000 rewards to members.
Return on Time – Is it an hour of your life for $2.00 or truly a fifteen minute survey?  We find out if the Return on Time (similar to Return on Investment) pans out.  Surely, some will be better than others for not wasting yours. Basically, we've evaluated not only how much you actually get paid to take surveys but also how long it takes to earn that 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 As a sweetener, they’ll even give you $5 just for signing up.
One Poll is a company that was founded in the United Kingdom, but it’s also open to consumers in the United States and beyond. It claims to be recognized by Money Saving Expert, one of the largest consumer websites in that country, which is a reassuring recommendation. What I recognized about it is that the surveys are short and easy to complete, so ideal if you’ve had a hard day and don’t want to do anything too taxing. New surveys are added on a daily basis, and some are amusingly quirky.
Focus groups are very different from pilot tests because people discuss the survey topic or respond to specific questions in a group setting, often face to face (though online focus groups are sometimes used). When conducting focus groups, the surveyor typically gathers a group of people and asks them questions, both as a group and individually. Focus group moderators may ask specific survey questions, but often focus group questions are less specific and allow participants to provide longer answers and discuss a topic with others. Focus groups can be particularly helpful in gathering information before developing a survey questionnaire to see what topics are salient to members of the population, how people understand a topic area and how people interpret questions (in particular, how framing a topic or question in different ways might affect responses). For these types of focus groups, the moderator typically asks broad questions to help elicit unedited reactions from the group members, and then may ask more specific follow-up questions.
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!
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.
