Answer 1

How to explain this... =/

Answer 2

i get that it issomething like ,.... Suppose the fire department mandates that all fire fighters must weigh between 150 and 250 pounds. The weight of a fire fighter would be an example of a continuous variable; since a fire fighter's weight could take on any value between 150 and 250 pounds.

Answer 3

Not continuous variable:
Number of oranges
Why? Well, the values that that variable can take don't "flow" They go; 0, 1, 2, 3, 4
could the value for number of oranges be between 3 and 4? Nope.

Answer 4

With a continuous variable, if you tell me two possible values for that variable, I can tell you another possible value that is between them.

Answer 5

So, height, for instance. You might think it's not continuous; 5'2'', 5'3'', 5'4'' etc.
However, it's continuous. If you tell me 5'2'' and 5'3'', a height that would be between them would be 5'2.5''
If you pick 5'2'' and 5'2.5'', I could pick a height that is between them as 5'2.3''

Answer 6

I'm curious what kind of course you're in. It's all statistics, right? But the topics you're asking about are all over the place.

Answer 7

Is it a go at your own pace kind of thing?

Answer 8

Answer 10

so what car can go from 0-100
tellephone number 0-9
the rest idk.

Answer 11

Let's start with the race car. Think about the two speed 33 and 34 mph. Could a car do a speed that is between those two speeds?

Answer 12

negative..

Answer 13

idk if you wanted to get technical it could

Answer 14

It could =) and I do want to get technical haha.

Answer 15

ohhh okay lol.. technical it is then.

Answer 16

So the car speed variable. Do you think you could pick two speeds so that I wouldn't be able to pick a speed that was between them?

Answer 17

idk that sounds weird,... like 20-21

Answer 18

I would pick 20.5 mph

Answer 19

what if it was 20.3

Answer 20

not 20.5

Answer 21

that is another speed between them, yes.

Answer 22

okay lol so it doesnt matter

Answer 23

We can keep going if you want to pick two more speeds for me =)

Answer 24

I will try to give you a speed that is between them.

Answer 25

I think we can move past the car haha.. so does all this speed stuff indeed make it a continuous variable

Answer 26

Yeees =)

Answer 27

I don't know if I'm explaining it well, but the fact that there is always some speed between two speeds makes it continuous.

Answer 28

For comparison, consider the variable number of children.

Answer 29

telephone numbers can be multeple numbers in a set of 7 numbers

Answer 30

thats continuous right

Answer 31

Can you give me two possible numbers of children so that I could not tell you a possible number between those two?

Answer 32

i could but that does nothing for me but get confused

Answer 33

im confused again lol

Answer 34

-_-

Answer 35

Hey! How many pizzas should we order?
Joe: I think we should order 2
James: I think we should order 3
Me: I think we should order some thing between 2 and 3 pizzas.
Everyone else: You're retarded.

Answer 36

Why am I retarded? Because you can't order 2 and a half pizzas.

Answer 37

pizzas is a noncontinuous variable.

Answer 38

that is retarded he should just get one large an a small or a large an medium. thats in the middle kinda

Answer 39

ahahah I like your creative solution, but that's not the point =)

Answer 40

Suppose it's Little Ceaser's hot n' ready, and there's only one size.

Answer 41

Answer 42

So cute. -_-

Answer 43

lolol ok ok :D ,... serious now... haha

Answer 44

so are all of them continuous cuz i cant cut any in half but each has a number in between

Answer 45

except the number of votes you cant have half a vote.

Answer 46

YEEEEAH! That's the whole point.

Answer 47

Number of votes is definitely non-continuous. You can't have half a vote.

Answer 48

Take another look at telephone numbers... =/

Answer 49

Answer 50

why cisnt telly numbers one? it has all kinds of numbers in between!

Answer 51

Oh yeah? What about these two telephone numbers:
123-4567 and 123-4568
What is a telephone number between those two?

Answer 52

hehe,... i didnt think about it like that,. alright i see the situation there

Answer 53

In general, if you could list all of the possible values for a variable, then it is not continuous.
Also, if it is a counting variable, then it is not continuous.

Answer 54

goch ya.!
