I thought it was B, but I guess not, but why would it be A without a 1....  I don't think they would use 00,10,20 etc?

Ah okay, so we cover everything even if it's not there huh?   Thanks.

jim_thompson5910 · Answer

the stems make this

0
1
2
3
4
5
6
7
8
9

Then you add the leaves



0| 0 0 0
1|
2| 3
3| 5
4|
5| 0
6| 5
7| 6
8| 7
9| 0

Okay, thanks :).

jim_thompson5910 · Answer

yes, even if there aren't any numbers like 40, 41, ..., 49 you still place a stem for 40 because you'll see how the data is laid out and how the distribution looks (ie how spread out things are)

konradzuse · Answer

yeah that makes sense.
