When the SAT asks you about mean, median, or mode, it’s just testing your ability to handle basic math concepts—ones you’ve probably been using without realizing it. But when test anxiety or SAT anxiety starts to whisper, “This is harder than it looks,” don’t fall for it! These are some of the easiest points you can grab on the SAT, and I’m here to show you how.

Let’s break down these three terms and learn how to calculate them step by step.

Step 1: The Mean (a.k.a. the Average)

The mean is just a fancy way of saying “average.” It answers the question: If we split everything evenly, what would each person (or thing) get?

How to Calculate the Mean:

  1. Add up all the numbers in the set.
  2. Divide the total by how many numbers there are.

Step 2: The Median (The Middle Value)

The median is the middle number when the numbers are arranged in order. It’s like the VIP of the group—the one standing right in the center.

How to Find the Median:

  1. Put the numbers in order from smallest to largest.
  2. Find the middle number.
    • If there’s an odd number of values, the middle one is the median.
    • If there’s an even number of values, take the average of the two middle numbers.

Step 3: The Mode (Most Frequent)

The mode is the number that shows up the most in a data set. Think of it as the “most popular kid in school.”

How to Find the Mode:

  1. Look for the number that appears the most.
  2. If no number repeats, there’s no mode.
  3. If multiple numbers repeat the same number of times, you can have more than one mode.
