What is a statistic, actually? It's a number that summarizes a pile of data in a useful way — and it turns out you already use them constantly, whether you're apartment hunting, grading a stack of exams, or trying to figure out which of your pottery mugs is the bestseller.

In this video we follow you through an imaginary life in Big City, USA (the air smells like hot dogs, sorry) and meet the most common statistics along the way:

• Mean — the average, and why a few mansions can throw it off
• Median — the middle value, and when it's the better choice
• Min and Max — the range of your data
• Variance and Standard Deviation — how spread out things are
• Mode — the most common value, for when averaging makes no sense
• Skewness and Tails — when your data leans one way
