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.
The only way to make this work would to be a serious survey junkie who can dedicate hours to the work, which defeats the purpose of a side hustle entirely. What’s worse is the idea that you can’t adequately plan your time—a survey might take twice as long as it says or five times as long. That kind of unpredictability means this isn’t a side hustle you can rely on.

“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.
