# Homework Help: Stem and leaf question! basic stats

1. The problem statement, all variables and given/known data
When constructing a stem and leaf graph I'm confused on how to label the stem and leaf still.

For example:
On page 20, number 12 in section 1.2:

The observations look like this:
.31 .35 .36 .36 .37 .38 .40 .40 .40
.41 .41 .42 ...

We were told to use repeating stems so I did the following:
3L|1
3H|56678
4L|000112222234
4H|5667888
5L|144
5H|58
6L|2
6H|6678
7L|
7H|5

L meaning (0,1,2,3,4)
H meaning (5,6,7,8,9)

Now the stem be the Tenths
The leaf be Hundredths?
because the stem is like .10 and the leafs are .01
That makes sense after someone explained it to me.

3. The attempt at a solution
But when I was looking at number 33 on page 31
the observations looked like this:

389 356 359 363 375 424 etc
now from this it looks like you would divide the steam and leaf like
38|9
35|69

I have the answers and the book did it as shown above.

What confuses me is that the book says the stem is the "ones" and the leaf is the tenths.

Wouldn't the stem be the Hundreds
and the leaf be the ones?
Because
389
3 is in the hundreds
8 is in the tens
9 is in the ones
so if they are breaking it up like 38|9
38 is in the hundreds
9 is in the ones correct?

So how would they get Stem being the ones and the leaf being the tenths?
