Imagine you’re averaging house prices in your neighborhood. One mansion sells for $10 million. Suddenly, the average says every house is worth $500,000. Total lie.
That’s the outlier trap. A single crazy-high or crazy-low number yanks the average around like a puppy on a leash. It’s hilarious—and dangerous.
Excel doesn’t judge. It just computes. So if you have a column of ages that includes a 102-year-old grandma and a 5-year-old toddler, the average age might say “48.” Is that useful? Maybe. But it’s also weirdly satisfying.
AVERAGE vs. Its Cousins: MEDIAN and MODE
MEDIAN is the cool, calm sibling. It finds the middle number when you sort the column. Outliers don’t bully it. So for that mansion neighborhood, MEDIAN might say $250,000—way more honest.
How to calculate average in a column based on criteria in another
MODE is the party animal. It finds the number that shows up most often. If your column has ten 7s, MODE screams “SEVEN!” like a bingo caller. It’s oddly thrilling.
But for pure, everyday muscle, AVERAGE is your go-to. Just know its flaws—it’s like trusting a friend who’s great at math but terrible at emotions.
