To start this problem, i'm going to look for the mean first.
00:03
The mean is adding up all the numbers and dividing by how many numbers there are.
00:08
So i'll start by adding 0 .9, 0 .5, 0 .7, 0 .4, 0 .3, and 0 .2.
00:21
And i get the answer of 3.
00:24
I'll take this answer 3 and divide by how many numbers there are.
00:28
1, 2, 3, 4, 5, 6.
00:30
So i'll divide by six.
00:32
3 divided by 6 is 0 .5 or 0 .5.
00:38
This is the mean.
00:40
The median is the middle number when all the numbers are in numerical order.
00:46
So i'll start with my lowest number, which is 0 .2, and work my way up.
00:51
0 .3, 0 .4, 0 .5, 0 .7, and 0 .9 .9.
01:01
One, two, three, four, five, six, one, two, three, four, five, six, just to make sure i have them all.
01:08
I want to count them...
