## rebecca1233 2 years ago For a stem-and-leaf plot, how many stems would you make out of this data set? 46, 69, 43, 79, 72, 55, 56, 47, 69, 49, 55, 45, 65, 64, 46 4 5 6 7 @tafkas77

hello?

3. tafkas77

Unfortunately, I am not all too familiar with stem and leaf plots anymore. I haven't used them in a while; let me do a little research and see if I will be able to help on this. If I can't, I'm really sorry about that; but there are plenty of users online who will be able to help with this! :)

4. tafkas77

Hmm... I'm thinking you could make about 4 stems here; but I need to make sure I'm looking at this right. do you understand anything about stem and leaf plots or are you completely lost?

5. rebecca1233

no i am lost lol

6. tafkas77

That's fine! i think i will be able to help you out

7. tafkas77

Yes, I understand this now. Please give me a sec to type this up. :)

8. rebecca1233

alright :)

Stem and leaf plots are organized by "stem and by leaf" in the fashion of a t-chart. This helps to group certain areas (the stem) and show the differences (the leaves). The "stem" is going to be on the left side, the "leaves" on the right. Ex: 12, 13, 14,15, 21, 22, 23, 24 There's going to be 2 stems here. There are two groups: the tens (12, 13, 14, and 15) and the twenties (21, 22, 23, and 24.) The stem and leaf plot is going to look like this: |dw:1363018504738:dw| The "stems" organize the groups (1 for the tens, 2 for the twenties) and the leaves show the different numbers within a group. The stems take the first number in each digit. Do you get it?

10. rebecca1233

yes but there is no answer option for 2

11. rebecca1233

options r

oh! That was just an example, rebecca. :) Now on to YOUR question: 46, 69, 43, 79, 72, 55, 56, 47, 69, 49, 55, 45, 65, 64, 46 To make this question easy, just look at the first digit of each number in the list. That is how you find the stems. I see a stem right here: |dw:1363018803635:dw|

14. rebecca1233

alright

15. tafkas77

So that means we have at least one stem. Let's look for others. To mkae it easy, we can take off the 40's: 69, 79, 72, 55, 56, 69, 55, 65, 64, 46 |dw:1363019088569:dw|

16. rebecca1233

alright :)

17. tafkas77

Now let's see if there are any other stems. Do you see any, rebecca?

18. rebecca1233

no.

19. tafkas77

Hmm? I guess I haven't done a magnificent job of explaining things. Look at this number: 24 You see how it's first digit is 2, and it's second digit is 4? Well, if I wanted to put 24 in a stem-and-leaf plot, I'd have to use it's first digit, 2, as a stem, and it's second digit, 4, as a leaf: |dw:1363019541759:dw|

20. tafkas77

If I wanted to add more numbers, like 25, 28, and 30, I'd have to sort them out:|dw:1363019613615:dw| Do you get this?

21. tafkas77

Aaaand.. she's gone. Well, I tried. :) Hopefully anyone else who sees this question will understand what I was trying to do! :)
