Statistics is very intimidating to me and is kicking my ass this semester, so writing these blogs and relating them to something fun really helps me commit it to memory. So today I am introducing the Three Musketeers of Math: Mean, Median, and Mode. These swashbuckling statistics will help you understand any dataset like Zorro deciphers a secret message.

Meet the Crew

  • The Average Avenger: Mean is the sum of all the values of your data divided by the number of values. Think of it as sharing a pizza equally among your friends. Everyone gets a slice. 
  • The Middle Mastermind: Median is the value that splits your data in half when ordered from least to greatest. Imagine lining up your friends by height. The median friend is smack dab in the middle, not the shortest or the tallest.
  • The Most Popular Posse: Mode is the value that appears most often in your data. It's like the friend who always shows up to parties, the life of the statistical soiree.

When to Call on Each Musketeer

Each Musketeer has their strengths and weaknesses. Mean is great for normally distributed data - think bell curve, but gets thrown off by outliers- think your friend who brought three extra pizzas - skewing the average. The median shines when you have skewed data or outliers, but it doesn't consider all the values like the mean does. Mode is all about popularity, but it can be unreliable is there's no clear favorite value- think of friends who are all equally awesome in their own way.

The Musketeers in action

Let's say you're tracking your video game scores: 10, 20, 30,30,40,50


  • The mean:( 10 +20+30+30+40+50) /6 = 30
  • The Median: Order the scores (10,20,30,30,40,50) the middle value is 30.
  • Mode: 30 appears twice, making it the most popular score.
 

The Mean, Median, and Mode are not rivals, they're complementary! Use them together to paint a richer picture of your data,
