The Definition Of Mean,Median,& Mode?

Question

Okay Im Kinda Doing My Homework But I Forgot What Mean,Median,& Mode Mean So I Cant Really Do My Homework

PLEASE HELP!

Answer 1

mean - add them all up and divide by the number of items you have

median - put them all in order, least to greatest, and the median is the middle number (or the mean of the middle two numbers if there is no middle number)

mode - the one that occurs the most, e.g. if you had 1, 1, 2, 2, 3, 3, 3, 4, 4, the mode is 3, because there are three threes and only two of the others.

Answer 2

Mode:  http://en.wikipedia.org/wiki/Mode_(stati...

Mean:  http://en.wikipedia.org/wiki/Arithmetic_...

Median:  http://en.wikipedia.org/wiki/Median

Just read the first paragraph or so.

Answer 3

ask your class mate

Answer 4

I can only help with mean.

The mean is average.

Answer 5

Mean: add them all together and divide by the number of "numbers" ex: 1, 2, 3,4,5 ......1+2+3+4+5+15....

15/5=3....so 3 is the mean

Median: the middle number in an ordered set of data ex. 1, 2, 3, 4, 5....3 is the median

Mode: the number that appears most often ex: 1, 2, 2, 3...2 is the mode.

Answer 6

mean is when you add all of them and divide by how many numbers there are

median is the middle number, you cross off a number on each side

mode is the number that shows up the most

Answer 7

mean is the average....add all the numbers, and then divide by how many numbers there are...

median is the middle number....put all the numbers in order from least to greatest. if there are two middle numbers, take the average (mean) of the two, and thats the median

mode is the most common number

Answer 8

mean = the average

median = middle number

mode = the one that shows up the most

Answer 9

Mean= Average score you add up the scores and divide it by how many scores there are e.g 5,8,11       5+8+11 divided by 3= 8

Median is the score in the middle. e.g 5,8,11,10,14,16,13 just cross out numbers from both outsides until you have 1 left in middle. Its 10 see how you can count 3 numbers to either side of it.

Mode= Number that occurs most, e.g 5,6,7,5,5,7,8,5, its obviously 5

Answer 10

mean...average...ex: 2+4+5=11...then divide by the amout of #'s u added..... 11 divided by 3

median is the middle number but u have to put them in order from least to greatest and if 2 numbers are in the middle then add those 2 numbers then divide by 2

mode is the easiest it's the number that appears the most

Answer 11

Mean -   you add all the numbers together, and then divide that number by the total amount of values..

for example..

2, 4, 6, 4

2 + 4 + 6 + 4 = 16

16 divided by 4 (because there are 4 numbers)

4 is the mean of those numbers

Median -  the middle number

1, 3, 5, 7, 9, 11, 13

7 is the median

Mode -  the number that appears most often

1, 5, 1, 8, 12, 1

1 would be the mode..

i hope this helps!

Answer 12

mean, that's the average. you have to get the total of all the samples divided by the number of samples. mode, i think is the total between the lowest and the highest. median, its when you rank the samples and you can get it by having the middle most sample in the rank

Answer 13

Mean - average

Mode - the number that appears the most in a discrete range of finite numbers.

Median - If you arrange the numbers in the set from highest to lowest or lowest to highest it would be the number in the very middle... if you have an even number of items in the set then take the two middle numbers and average them.

Answer 14

Mean is  average of the numbers.

Median is center of the numbers if they were in numerical order.

Mode is the number that comes up most.

Answer 15

All three of them are types of averages.

MEAN = is when you add them all up and divide them up by how many there is. For example if you had a sequence of:

1, 1, 1, 2, 2, 2, 3, 3, 4

And you had to find the mean, you'd all all those numbers up and divide them by how many numbers there are- in this case, there are three 1s, three 2s, two 3s and one 4.

MEDIAN = remember this because "median" sounds vaguely like "medium" - which it is. it's the middle number of a sequence.

MODE = the modal number is the most- sounds vaguely like mode, huh? so if you had seven 9s in your sequence but only two 4s, then 9 would be the modal number.
