Some statistics to start:
- In 68% of drowning fatalities, people were not wearing life jackets
- In 68% of fatal police officer shootings, the police officer was not wearing a bullet-proof vest
- The most popular day to read blog posts is Thursday
- The most popular days to use Twitter are Wednesday and Thursday (from this Tech Crunch post on Twitter statistics)
Human behavior demonstrates many statistical consistencies. To truly understand your customer you need to take the time to discover the numbers that help explain their behavior. As Lord Kelvin said, "when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind".
