So we have a question about a stem and leaf plot.
00:04
And the question that has to do with like how many data values are in the data set.
00:08
So honestly, the way that it came out is very confusing.
00:13
I'll just tell you what it looks like.
00:15
When you copied it and it says four and then there's a pound sign and then a line that says one, one, two, five, seven, seven, eight, nine, five.
00:25
And then there's another pound sign and the line in zero, zero, zero, one, two, two, two, three, a bunch of fours.
00:34
I think there's five of them, and then a five, a six, seven, seven, six, another pound sign, another line, and then zero six, seven, eight, nine, seven, then another pound sign, a line, and three, eight, nine.
00:54
So just so you can see, this is going to be difficult for me to figure out exactly what your data set looks like.
01:00
However, i'm happy to help you learn how to look at a stem and leaf plot and figure out how many data values there.
01:08
So stem and leaf plot is broken up into two parts.
01:12
There's the stem column and then there's the leaf section.
01:18
So the stem is usually used for the tens digit.
01:23
So let's say we start at three.
01:26
They oftentimes will go in order, three, four, five, six, 7, we'll use those.
01:33
And the 3, this 3, would be referring to 30 versus like the 7 would be referring to 70.
01:44
The leafs are all about the units.
01:48
So we see them in order.
01:50
If we say 1, 1, 4, 9, then if we look at this value, what we're actually talking about is the 30 and a 4.
02:03
So we're really talking about the number 34 versus the number right next to it, this 9, that would be the number 30 and the 9...
