00:01
So i started by separating the data.
00:03
There were 21 numbers.
00:04
So i put 10 in order on the left.
00:07
The one that's in the middle, in the middle, and that would be the median.
00:14
And then the upper 10 on the right.
00:17
So you need the median.
00:19
You need the middle of the lower set.
00:23
So if there's 10 numbers there, 1, 2, 3, 4, 5.
00:26
It'll be in between 160 and 161.
00:30
So there'll be 160 .5.
00:32
And same for the upper.
00:38
So it'll be in between 184 and 188, so that would be 186.
00:43
Now, if you're not sure, you can add the two numbers and divide by two.
00:49
And then you also need the lowest number, 154, and the highest number, 191.
00:57
So then to do your stem and leaf plot, you need a number line.
01:04
So our lowest is 154, so we'll start here like this will be 1501.
01:11
And our highest is 191, so we'll try to go 195 up there...
