In math, why does there always have to be a mode?

Question

When finding mean, median and mode, there always is a mode, even if the two most common numbers have the same number. Why?

This is a question my teacher asked for hw!

Answer 1

not always

a number can appear once and not twice or more, and there wouldn't be a mode

for example

3,5,6,8,9,10

there isn't a mode

Answer 2

It is like a tie for first place. If two numbers appear the same number of times and are the most common in the group they are tied for being the mode. It make sense to me and I am not sure why you are confused.

Answer 3

A set of data has no mode, one mode, two modes, or more modes. It is the most often occuring. If each number in the set of data only appears once, then there is NO mode.

Answer 4

Uh, a mode is just the number in a set that appears most frequently, so... assuming that it isn't a null set, there has to be SOMETHING that would be the mode, even if it's an infinite tie between an infinite number of modes. o.o (but that's not really important...)

Answer 5

its just like another way... mode is like used to get em.... the most appearing number and it is clearly different from average

u will use mode later on if u study furthur math. Some teachers also grade tests using mode :)

Answer 6

Personally, I prefer ala mode

Answer 7

to learn in maths obviously if you dont have a mode you cant even sell things and i even asked my bothers ad they told me the answers and you wouldn't ever get twin brothers like i have!!!

SO BUGG OFF!!!!!

Answer 8

why not its easy to find the mode (the numeber that has the most of its self)

Answer 9

Because your mom made a mode with me.

Answer 10

just to see what number occurs the most i guess
