to determine this, think about the type of measurement used: time in this case
anonymous
  • anonymous
you can break your commute to work down to even the smallest measurement of time: so we can start with hours:minutes:seconds:milliseconds...

well, first what do you think it is?
anonymous
  • anonymous
idk
anonymous
  • anonymous
a discrete variable is one that finite. meaning that you only have a certain number of possible values. while a continuous variable is essentially finite.
anonymous
  • anonymous
*infinite, sorry
anonymous
  • anonymous
k. so im still confused!
anonymous
  • anonymous
all right. let's consider finite first.
anonymous
  • anonymous
if you have a survey, and there is question that asks you to rate how much you enjoyed the new Fast and Furious movie, on a scale from 1 to 5. with 1 being you hated it, and 5 being you loved it
anonymous
  • anonymous
the choices: 1, 2, 3, 4, 5. represent discrete values
anonymous
  • anonymous
you can't say you liked the movie 4.3423
anonymous
  • anonymous
ohk so its discrete?
anonymous
  • anonymous
the survey example is discrete
anonymous
  • anonymous
ohk what about the origonal question
anonymous
  • anonymous
so now. if you could be more specific. and you could choose any value from 1 to 5, then the choice of 4.3423 would be allowed
anonymous
  • anonymous
and in that case basically any number, 4.3232593923954350345 for example, could your choice
anonymous
  • anonymous
so you now have so many choices, essentially an infinite number of choices now, because the new survey scale is *continuous*
anonymous
  • anonymous
ok. im still confused. youved gotten me nowhere bud
anonymous
  • anonymous
OK, so now, let's look at X in your question, which is the amount of time it takes to get to work.
anonymous
  • anonymous
it may take you 5 minutes to get to work one day. it may take you 5 minutes and 11 seconds the next. i may take you 5 minutes 11 seconds and 15 milliseconds the following day
anonymous
  • anonymous
yes?
anonymous
  • anonymous
you are not limited to a few options (like in the first survey with 1,2,3,4,5), because the amount of time can vary greatly
anonymous
  • anonymous
continous?
anonymous
  • anonymous
well yes
anonymous
  • anonymous
does it make sense?
anonymous
  • anonymous
no. not really i quessed..
anonymous
  • anonymous
right ;) can you try to explain to me what discrete means?
anonymous
  • anonymous
fintite??
anonymous
  • anonymous
all right, so what is continuous?
anonymous
  • anonymous
unfinite.? but i dont nderstand what finite is reallly XD
anonymous
  • anonymous
ok finite sort of just means that you can count whatever it is
anonymous
  • anonymous
like in the survey, you could count the number of possible choices: there were only 5 (1,2,34,5) in the finite case
anonymous
  • anonymous
sorry about that, OK, so infinite sort of just means that you can't count whatever it is: in the case where you could now choose any value from to 1 to 5, like 4.23423545, you could also choose 4.3224545 or 4.3 or 3.2352345 or a 3 with however many numbers behind the decimal point
anonymous
  • anonymous
in that case you can't count the number of possible choices...there are an infinite number
anonymous
  • anonymous
k i thinkg i got it
anonymous
  • anonymous
all right. i hope this helped. I need to go now. good night and good luck
anonymous
  • anonymous
k thank you
