to determine this, think about the type of measurement used: time in this case
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?
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.
k. so im still confused!
all right. let's consider finite first.
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
the choices: 1, 2, 3, 4, 5. represent discrete values
you can't say you liked the movie 4.3423
ohk so its discrete?
the survey example is discrete
ohk what about the origonal question
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
and in that case basically any number, 4.3232593923954350345 for example, could your choice
so you now have so many choices, essentially an infinite number of choices now, because the new survey scale is *continuous*
ok. im still confused. youved gotten me nowhere bud
OK, so now, let's look at X in your question, which is the amount of time it takes to get to work.
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
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
does it make sense?
no. not really i quessed..
right ;) can you try to explain to me what discrete means?
all right, so what is continuous?
unfinite.? but i dont nderstand what finite is reallly XD
ok finite sort of just means that you can count whatever it is
like in the survey, you could count the number of possible choices: there were only 5 (1,2,34,5) in the finite case
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
in that case you can't count the number of possible choices...there are an infinite number
k i thinkg i got it
all right. i hope this helped. I need to go now. good night and good luck
k thank you
