Ultimately, it is very unlikely that participating in online surveys will provide you with a steady, livable wage. However, if you enjoy participating in online surveys (especially if you like the prizes, coupons, and other more typical non-monetary earnings), be sure to avoid questionable third-party sites. Look for real paid surveys online that don’t require you to invest money.
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.
“I participated in an in-home product trial study. A coffee machine company sent me one of the coffee makers along with about 200 coffee pods. I received $7 for completing 3 short surveys. Plus, after the study, the company said I could keep the coffee maker. So, I got like 4 mos of coffee for everyone in my household, a free coffee maker and $7!” - David W.
