Do you know how to read a stem-and-leaf plot, Absoluter?

OpenStudy (anonymous):

no

OpenStudy (goldphenoix):

If not, then the stem represent the tens place, while the leaf represent the ones place. So it's from least to greatest.

OpenStudy (anonymous):

ok

OpenStudy (goldphenoix):

Do you know how to find the median, now?

OpenStudy (anonymous):

no

OpenStudy (goldphenoix):

... The stem represent the tens place, and the leaf represent the ones place. Since the stem is increasing in each row, then that means that the data set is in order. So you cross out the least, and then the greatest, until you find the median.

OpenStudy (goldphenoix):

Alright, tell me, how many numbers are there in the stem-and-leaf plot?

OpenStudy (anonymous):

for the stem or leaf or both

OpenStudy (goldphenoix):

o.o? Both, I guess.

OpenStudy (anonymous):

28

OpenStudy (goldphenoix):

Hmm. That's not what I meant. |dw:1374635887108:dw|

OpenStudy (goldphenoix):

Okay fine. How many number are there in the leaf?

OpenStudy (anonymous):

23

OpenStudy (goldphenoix):

Great. So they're 23 numbers. Now if you cross out the number in the beginning, and the end, and repeat it, what do you get?

OpenStudy (anonymous):

45

OpenStudy (goldphenoix):

If you don't know what I mean, then I'll give you an example: |dw:1374636092025:dw|

OpenStudy (anonymous):

83?

OpenStudy (anonymous):

correct answer?

OpenStudy (goldphenoix):

Close.

OpenStudy (anonymous):

minus 2 or plus 2

OpenStudy (goldphenoix):

I'll give it to you, it's 84. There's 23 numbers in total. So cross out 11 in the beginning, and the 11 at the end. You'll end up with 84.

Do you know how to read a stem-and-leaf plot now?
