Once upon a time, I took a job as a pollster. I went door to door, surveying people high and low, near and far, all throughout the kingdom, gathering statistics as I went.
One day, I came upon a quaint little cottage in the woods. I knocked on the door, and had the most unusual visit. During that stop I learned the following:
First, I learned that only one out of every seven dwarfs is happy. In contrast, one out of seven has anger management issues.
In two out of every seven dwarfs, I observed serious medical issues, ranging from narcolepsy to severe allergies.
14% of all dwarfs wear corrective lenses.
1/7th of the respondents would only nod his head in response to the questions.
Finally, this survey has a margin of error of plus or minus one, as the last respondent repeatedly withdrew, making it tough to discern his answers.
