Fun Facts
"The term 'average' comes from the Arabic 'awariyah', which referred to damaged goods in maritime trade."
"In a perfectly symmetrical distribution (like the Bell Curve), the mean, median, and mode are all identical."
"Statisticians often use the 'weighted mean' if some grades are worth more than others (like a final exam vs a quiz)."
