TEST - Is Self-Reported Data Reliable

When you ask people for information about themselves, you run the risk of getting flawed data. People aren’t always honest. If you ask someone who they're going to vote for, they may tell you the truth - or they may lie. This is one reason why polls may be inaccurate.  

Takeaway: Whether you're looking at pre-election polls or exit polls, know that people may not be telling the truth - which can skew the results.
