Identify data quartiles

“

- [Instructor] Large datasets often contain values that can be divided into groups. For example, some of your products might sell extremely well while others sell just a few units a year. One way to analyze your data is to divide values into four groups representing the top 25%, 50%, 75%, and then the rest of your data. These groups are called quartiles. In this movie, I'll show you how to identify the 25%, the 50%, and the 75% quartile values in Mathematica 11. I need to enter in some data to work with, so I'll create a list, and I'll name it list1, then give an equal sign, and I am enumerating a list, so I'll a type a left curly bracket, and then the values are 14, 18, 2, 19, 25, 36, 47, and 60, and I'll close my list with a right curly bracket, and shift + enter. After I press shift + enter, I see my list. I can display the quartile values using the quartiles keyword, so I'll just type that. It's Quartiles with a capital Q, A-R-T-I-L-E-S, then a left square bracket, and the name of…
