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.
Unlike some of the other sites, with Inbox Dollar, you essentially sign up to take advantage of whatever Inbox Dollar makes from their advertisers.  They will send you emails which they get paid per receipt of you reading them or clicking a link.  In turn, they give you a cut.  Not to ruin your day but it's a rather small cut.  The links that end up paying out the most usually have some stipulations attached – such as signing up for a service.  This can end up being a lot more hassle than its worth and we recommend you pay VERY close attention to the stipulations.

If you're looking to make money by completing surveys online – this site will not be very helpful for you.  Like the previous sites, they will take, retain, and sell your information to anyone that waves a dollar in their faces.  UNLIKE previous sites reviewed, they hide their consent for that information.  It's buried.  So not only do you make silly reward points that don't translate to cash but every third party service and product solicitor has your personal information.
Most reviewed paid survey sites effectively promise not to share personally identifiable information or not to share it without your consent. It's an industry standard by which legitimate marketing research firms are bound. But many membership sites reviewed don't make either promise or do so only in a limited or wishy-washy way. Unauthorized go-betweens don't have to honor marketing research privacy standards.
