Where is the median in this stem-and-leaf plot?
Madam Do you know the formula of median ?
do i put the stem in order too? or just the leaf part>
Madam it's correct.
which part.. do i put the stem in order too? or just the leaf part? then what do i do cause even if i put that in order i wont get a big number like that for the answer
Yes Its correct @ParthKohli
there is 18 numbers if i put stem and leaf plot in order together
it goes 0,1,1,2,3,3,3,4,4,5,5,5,6,7,7,8,8,9
u arent telling me which part is correct? wat do i do after i get that ?
how did u get that? cause i put em in order and crossed them out and 5 was in the middle
@goformit100 you need to explain not just give me the answer... wt do u not understand about that
Now after getting the middle term The find the median.
I got 5 for the middle term am i correct bout that
Yes Its correct now
but 5 is not the answer? so wat do i do with the 5 ?
@Koikkara HELP HELP.... I have gonna Stuck :'(
I thought you knew :/ @Koikkara hlp please
help someone!! Explain!!
well, first i'll tag some genius, n then give a try...... @AravindG @TuringTest @amistre64 @Ashleyisakitty @churrity
You going to help me ?
now that i got all the way down to the end, i forgot the question ....
http://www.xtremepapers.com/revision/gcse/statistics/stem_and_leaf_plots.php may help with the stuck......n So sorry me a bit weak in maths....ask bio....@!!
how many leafs are there? entotal?
correct, 13/2 will get us near what we want then what is 13/2?
To find the median of a steam and leave diagram is to cross out each number going in a diagonal form. Thats a bit confusing to understand so im going to include a drawing of what I mean. |dw:1363112492216:dw|
13/2 = 6.5 since it has a decimal on it .... we round up to 7 the median is the 7th leaf
why do u cross only those out for ?
4 | 2 4 ... 2 leaf 5 | 1 3 ... 4 leaf 6 | 1 5 ... 6 leaf 7 | 0 3 8 ^^ 7th leaf lets go with 70 as the median
if we had just written these out, itd be the 7th number 1 2 3 4 5 6 7 42 44 51 53 61 65 70
but dont u cross the top 2 and top bottom so it would be the 6 row
in ur example where u crossed things out im lookin at the stem side u cross 2 and cross 2 at bottom so its in row 6
thats where im confused
i dont go with the crossing things out method ... i simply count
there is 13 on the leaf side
1 3 are 2 different leafs. stem | leafs S | L1 L2 L3 L4 ... a leaf is usually a unit value. a stem is usually a base 10 value
42 43 45 46 would stem and leaf as: 4 | 2 3 5 6 its just a way of representing the data points
so u just cross em out but 7 is still at the bottom..idk im confused lol
lets list your numbers instead of leafing them ok? \[42~ 44~ 51~ 53~ 61~ 65~ 70~73~78~83~85~87~89\] one way to find the median is to find the number in the center .. we can do that by crossing off positions in a symmetric manner \[\cancel{42}~ 44~ 51~ 53~ 61~ 65~ 70~73~78~83~85~87~\cancel{89}\] \[\cancel{42}~ \cancel{44}~ 51~ 53~ 61~ 65~ 70~73~78~83~85~\cancel{87}~\cancel{89}\] \[\cancel{42}~ \cancel{44}~ \cancel{51}~ 53~ 61~ 65~ 70~73~78~83~\cancel{85}~\cancel{87}~\cancel{89}\] \[\cancel{42}~ \cancel{44}~ \cancel{51}~ \cancel{53~ 61~ 65}~ 70~\cancel{73~78~83}~\cancel{85}~\cancel{87}~\cancel{89}\]
if you follow this on the stem leaf .... you get Ashleys suggestions
oh i i see u made them numbers not separte numbers
like not just 4 , 2 , and so on u made it 42 and etc
thats where u get 70
thats where i did it wrong lol
take the stem, and attach it to each leaf 7 | 0 3 8 represents: 70 73 78
yeah i wasnt doing that lol i feel dumb haha
:) youll do fine after this
lol yeah that i understand now haha .. thank you :) thank you for working with me haha ..
youre welcome, i do have to be going for today so i wish you the best of luck
