and even if it was 25 you would divide it by 5 to get 5 and that isn't a option

@Preetha
OpenStudy (anonymous):
keep in mind that the first amount of tv's is 0 but you do have to add it when you devide by the number of households
OpenStudy (anonymous):
the mean is the most often used number, so you can find the answer by taking every tally and multiplying it by the number of sets, then divide it by the number of students.
(0*1) + (1*8) + (2*9) + (3*4) + (4*3) = 50
50 / ( 1 + 8 + 9 + 4 + 3 ) = 2
OpenStudy (anonymous):
it says WORKING° TV's also

no that is mode
OpenStudy (anonymous):
assume all listed tv's are working
OpenStudy (anonymous):
mode is most often used, sorry, mean is the average.
OpenStudy (anonymous):
the mode would be 2 as well though.
OpenStudy (anonymous):

doesnt*
OpenStudy (anonymous):
he does count, he has 0 working T.V.'s in his house, so his data still matters.
OpenStudy (anonymous):
it does count towards the number of households, not towards the tvs
OpenStudy (anonymous):
hold on a minute
OpenStudy (anonymous):
so then that is 24 / 5

24/5?
OpenStudy (anonymous):
divided
OpenStudy (anonymous):
why would it be 24/5? xD
OpenStudy (anonymous):
24 ÷ 5
OpenStudy (anonymous):
I explained how the mean works and how you can find it with data sets, look at my first responce.

OpenStudy (anonymous):

OpenStudy (anonymous):
simple
OpenStudy (anonymous):
but, that doesnt work

but you're finding the average number o T.V. sets, not the average number of people with a non-zero amount of T.V. sets in a given classroom.
OpenStudy (anonymous):
OHHHHHHHH, I GET IT NOW
OpenStudy (anonymous):
that, I feel like an idiot, maybe I am D:
OpenStudy (anonymous):
you're actually counting each T.V. set, so the long math would look like
0+1+1+1+1+1+1+1+1+2+2+2+2+2+2+2+2+2+3+3+3+3+4+4+4 / however many students there are
OpenStudy (anonymous):
needs more 2s n' stuff, but you get the point, rather than typing two nine times, you can just type (2*9)
