Question: What is a normal distribution?
Example
“A normal distribution is like the bell-shaped curve you see for many attributes– it’s centered on the mean, and is symmetrically distributed outwards indefinitely. Most importantly, normal distributions make up the backbone for most statistical testing, and is why we can make assumptions about a population based on a variety of samples.”
Tips
- The typical bell-shaped curve.
- Properties include unimodal, symmetrical, asymptotic.
- Mean, mode, and median are equal.
