Question

What are the differences between
Range
domain
mode
median
mean
?

Answer 1

Do you know the basic meaning of any of the terms?

Answer 2

Median = middle value
Mode= most repeated value
Mean = Average

Answer 3

mean is all the numbers added together and then divided by the amount of numbers. median is the midial number. mode is the number that accures the most times.

Answer 4

oh okay. yeah i remember that

Answer 5

i just get confused by which is which

Answer 6

Well, Range is when you take the largest number, and you subtract the smallest. Mode, is the most often, median is the middle number (found by ordering the numbers least to greatest and finding the middle), and mean is the sum of ALL numbers in the set, divided by the count :)

Answer 7

Whats the domain?

Answer 8

Ah. Well, domain is the input or horizontal axis and range is the output or vertical axis.

Answer 9

... what

Answer 10

domain is the set of all the possible inputs of a function.
for f(x) = 2*x. the domain are all possible x's, namely the real numbers R.

Answer 11

Ah, true, statistics, range has tro meanings in math... one in cartesian coordinates and one in statistics. Range can also be the difference in high to low, as YesThisIsDog is talking about. They are related concepts.

Answer 12

Okay... i get what range is. But im still kind of confused on domain

Answer 13

like, does it have to do with graphs? equations?

Answer 14

I'm studying for my keystones

Answer 15

Domain is correlated to functions, and graphs.

Answer 16

okay

Answer 17

Both. As a word, your domain is where you live and rule. So these are places you can do things and change things.

In math, the domain is where the INPUT to an equation is valid. It can be used there and causes valid output.

Answer 18

okay. so if the question asks to find the domain of an expression/equation?

Answer 19

To answer the second part of your earlier one, functions or graphs, how the domain relates to graph is the same way any other part of a function relates to a graph. A graph is just a visual representation of a function, equation, etc. A picture of the math.

If asked to find the domain, look for invalid input. The two big ones are divide by zero and negative, even roots.

\(\dfrac{n}{x}\) when the bottom is 0 the domain is invalid.

\(\sqrt{x}\) when \(x<0\) the domain is invalid.

\(\sqrt[3]{x}\) but cube roots can have \(x<0\)

Answer 20

OHHHH thank you so much!

Answer 21

That makes a lot more sense now

Answer 22

Yah, so just like in life, the domain is where it can live and do things. If it is not allowed, it is not in the domain.

Answer 23

thank you! medal to you!

Answer 24

can you help me with something else really quick>

Answer 25

For remembering mean, median, and mode... hmmm... you might want to find little stories to help with that. For example, the average was mean to me! Just that line can help with mean. The median line is in the middle of the road. The mode of doing things is the most popular way of doing them. Do you see how those relate to their mathematical meanings?

And you can always ask another question when you are done with one.

Answer 26

okay tahnk you

Answer 27

Order the following list of number from least to greatest:
SQRT 62, 7.7777 (repeating), 23/3, and 7.83 (repeating the 3)

Answer 28

With those, a lot of times the easiest thing to to just use a calculator to get them all in decimal form. Then you order them based on the decimal value.
