Okay, and your question, you're to create a stem and leaf plot for the data.
00:03
I have listed in the left.
00:06
So let's start with our stems.
00:08
You want to identify the lowest stem that you need.
00:11
I've identified the lowest value will be in the teens.
00:15
So i see a number with a one in front of it.
00:19
And we're going to have stems of two, three, four, five, and six.
00:25
I don't see any numbers in the 70s, so our stems are now covered.
00:29
And now what i want to do is i want to start meticulously going through and finding each value that should be in each stem.
00:39
So there's 16.
00:40
I don't have any other values that start with a 1.
00:43
So the only leaf we have is 6.
00:46
I'll cross that number out.
00:49
Now we'll highlight all values into 20s.
00:54
I'm going to do that first, just highlighting them.
01:00
Okay, now i want to get those in order.
01:02
So the lowest i see is 20, and there are 2.
01:05
Of them.
01:06
So that means two leaves of zero.
01:10
Then i see f23, which would be the next one, f25, and a 28.
01:17
Let's cross those values out.
01:21
And we'll move on to the 30s.
01:24
I'll highlight those in blue.
01:27
There's a 30, 30s.
01:37
Okay, i've highlighted all the 30s in blue.
01:39
The lowest 30 value i see is a 31.
01:43
Then i see 35s.
01:45
I see three of them.
01:47
So i should put five.
01:48
Three times.
01:50
Let's cross those out that we just used.
01:54
I see a 36 and a 38, two 38s.
02:03
So there's 138 and a second 38.
02:08
All right, let's move on to the 40s.
02:11
Highlight those in yellow.
02:26
Okay, so list our 40s out.
02:28
The lowest 40 i see is the number 40.
02:37
So we've used that one.
02:40
And now 42, i see, 43 there's no 44s there's a 45 there's a 46 there's three 49s one two three 49s and as i was working on those 40s i realized i missed a 20 value so i need a six in the 20s cross that out and now on to the 50s okay the lowest 50 value i see is zero then i have a 53, 55, a 56, and a 58.
03:48
Cross those out, and the remaining values are in the 60s.
03:52
I have a 60, so just a zero, i have another 60.
03:58
So there's one, 60, two 60s, then i have a 63, 64, and a 66...
