OpenStudy (anonymous):

can you see my attachment

OpenStudy (amistre64):

yeah, you got 4 stems; how many leafs you got?

OpenStudy (anonymous):

4

OpenStudy (amistre64):

.... its wasnt 4 the last time, it aint gonna be 4 this time; how many leafs you got?

OpenStudy (anonymous):

4 right ?

OpenStudy (amistre64):

lol ... no, stems are on the left; leafs are on the right; they even labeled them for you, you got 4 stems; how many blue numbers under the label of "leaf" do you have?

OpenStudy (amistre64):

you can see your attachment right?

OpenStudy (anonymous):

lol oh theres 4 numbers but do you count the 00 one? sorry if i sound like a idiot lol

OpenStudy (amistre64):

the 00 means: 90 and 90 stem leaf 9 | 0 0

OpenStudy (amistre64):

each digit under the leaf is a data point; the stem is the tens spot you got your 60s 70s 80s 90s for stems

OpenStudy (amistre64):

6 | 9 7 | 1267 means the numbers 69 71 72 76 77

OpenStudy (amistre64):

if you know how many leafs there are; you know how many data points you got and can find the one in the middle then

OpenStudy (anonymous):

okay i get it

OpenStudy (amistre64):

good, and 82.5 should be it if i remember this question from the last dozen times it was posted :) your teacher put you up to this i assume

OpenStudy (amistre64):

12 leafs / 2 = 6 ... 6 is a whole number which aint good for finding medians you want the middle of the 6th and 7th numbers 81 84 ^ 82.5
