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.
One example would be that a brand like Coke or Pepsi wants to know more about what kind of people are buying their beverages. They might want to learn more about the age, gender, income, or location of the people who like or dislike their products. They might use this for marketing purposes or to make decisions about their future products. Brands like this spend a lot of time and money investing market research to get your feedback. You just get money for doing them a favor – it’s a total win-win!
They are new to me. I did a search and wasn’t able to turn up much online, other than this – https://forum.surveypolice.com/index.php?/topic/4110-saw-an-advertisement-for-iglobalsurveys/. Someone thinks they are more of a “survey router,” not the same as answering Q’s directly for a survey panel. So I think I personally wouldn’t sign up, but as always I recommend that you do you your own research in addition to the research I’ve done.
It’s easy to earn cash for surveys. How much you get paid completely depends on how many paid surveys you attempt and complete. Each online survey has a different payout, with some offering as much as $50. Most will pay less, but also take less time. Expect to earn about 40 to 200 SB points per survey (100 SB = $1), with occasional opportunities with much higher earning potential.
