the characteristic bell-shaped curve that is symmetrical about the mean, with tails approaching plus and minus infinity ...

is a well equilibrated bell curve. Some data from real-world processes follow this pattern, making the normal distribution an ...

What does this complexity lead to? Francis Galton had a strong desire to explain continuous variation in terms of normal distribution (i.e., the bell curve). To understand the occurrence of ...

It's possible, but not common. This is a good time to revisit the difference between normal and average. Picture a nice bell-shaped curve and remember that for a given characteristic the normal ...
