Organizing Data Using Matrices
Now that we have gone through the basics of matrices, let’s work on how matrices are used to organize data. Suppose you have the following table:
|
Game A |
Game B |
Cans of Soda |
5 |
10 |
Juice Boxes |
7 |
44 |
This table represents the number of cans of soda and juice boxes sold at two basketball games at a local elementary school. We can now take this table and turn it into a matrix.
Matrices are named with a capital letter while the entries are named with a small letter. Analyzing the matrix we see that g11 = 5, g12 = 10, g21 = 7 and g22 = 44.
