Hey there! Let me explain to you what "quartile" means in a way that's easy to understand, okay?

So, imagine you have a group of friends and you want to divide them into small groups, but you want each group to have an equal number of friends. One way to do that is by using quartiles.

Now, quartiles help us understand how data or numbers are spread out in a set. Let's say we have a set of numbers, like 1, 3, 5, 7, and 9. To find the quartiles, we divide the set into four equal parts.

Here's how we find the quartiles:

First Quartile (Q1):

Think of the first quartile as the point that splits the first 25% of the data from the rest. If we have 20 numbers in our set, Q1 would be the value that is greater than 25% of the numbers and less than 75% of the numbers. It's sort of like dividing your friends into four groups and Q1 would be the point where the first group ends and the second group begins.

Second Quartile (Q2):

Here's where it can get a bit tricky but bear with me. The second quartile is also called the median. The median is the middle value of a set when the numbers are in order. So, if we have 20 numbers, Q2 will be the value right in the middle, splitting the set into two equal parts. It's like having your friends stand in a line, and Q2 would be the friend standing right in the middle.

Third Quartile (Q3):

Similar to Q1, think of the third quartile as the point that separates the first 75% of the numbers from the last 25%. It's like dividing your friends into four groups, and Q3 would be the boundary between the third group and the fourth group.

Now, sometimes there's another definition of "quartile" which refers to the actual values where these quartile points occur. So, when we say "finding the quartiles," we are not only talking about the points itself but the specific values in the set that represent those points.

In summary, quartiles help us split a set of numbers into equal parts, which can give us a better understanding of how the data is spread out. It's like dividing your friends into different groups, but instead of friends, we're talking about numbers here.

I hope that helps! If you have any more questions, feel free to ask. Understanding new words can be challenging, but together we can make it simpler!
