Pythagorean means is a fancy term that refers to a type of average that you can calculate using math. Let's imagine you have three numbers, let's say 2, 4, and 8. You want a number that represents all three of these numbers equally. The Pythagorean mean can help you find that number.
First, you would have to square each of the three numbers. So, 2 squared is 4, 4 squared is 16, and 8 squared is 64.
Next, you add up these squared numbers (4 + 16 + 64 = 84).
Then, you divide that total by the number of original numbers you had (in this case, 3), which gives you an average of 28.
Finally, you take the square root of that average (which is about 5.29) and that is your Pythagorean mean.
Basically, Pythagorean means helps you find a number that is in the middle of several numbers and represents them all fairly.
