All right, so let's talk about a lot of the data that you could use and could decide on how to do a graphical display.
00:09
So first, there were 20 states, and you'd want to find the mean.
00:16
The mean is the grand total, 331 .7, by adding up the 20 divided by 20.
00:24
So that's 16 .585.
00:28
The median is putting it in order, and it'd be the middle two.
00:33
The median is 10 .4 and the range would be the max minus the min and that's 10 .6 .2 you could do quartiles.
01:02
The median of the lower half is negative 3 .1.
01:12
The third quartile, which is meeting of the upper half of the data, is 32 .15.
01:30
You could just make some observations that 5, 6, 7 were negative and 13 were positive.
01:42
So a graphical approach would be like using a histogram.
01:52
And you can even use decimals for this.
01:54
You enter the data into a list...
