Okay, so in this table, i have three different states, california, florida, and texas, and five different months in the amount of foreclosures in each of these three states in these five months.
00:10
So i want to determine which month the difference between the foreclosures in california and florida was the greatest.
00:18
So what i could do is i could do california.
00:25
I have all my california matrices and then i could subtract the florida foreclosures and this will give me the greatest difference so in each month august, september, october, november, december i have the matrix for the california one 71 ,000 in august, 7 ,100 in august 3 ,300 in october 5 ,700 in september and october 5 ,000 in november and then finally 4 ,300 in december.
00:59
And then my florida matrix, same exact months, 3 ,500 in august in florida, 900, 2 ,400, and finally, 2 ,300.
01:12
So i'm just going to subtract this matrix to get my differences.
01:16
So when i'm adding and subtracting matrices, i have a 1 by 5 matrix.
01:20
So i'm going to end with a 1 by 5 matrix, and i'm just combining each of these terms.
01:25
7100 minus 3 ,500 is 3 ,600.
01:28
So this is a pretty good difference...
