Data can be distributed (spread out) like this "Bell Curve":
• The "Bell Curve" is the Normal Distribution.
• The yellow histogram shows some data that follows it closely, but not perfectly (which is ok).
Many things closely follow a Normal Distribution:
• heights of people
• size of things produced by machines
• errors in measurements
• blood pressure
• marks on a test
