Distributions (Normal, Binomial)

Summary

A normal distribution is the classic bell curve many real-world metrics approximate; a binomial distribution models the count of successes across repeated yes/no trials.

• 1Sketch a normal distribution and label the 68-95-99.7 rule.
• 2Identify a real metric you'd expect to be roughly normally distributed, and one that wouldn't be.
• 3Learn the basic shape of a binomial distribution and where it shows up (conversion rates).
