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

    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! :)

    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?

    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?

    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|

    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|

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

    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|

    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?
