What does 'Mean' mean in maths?

Question

Please help . have maths h/w and i have to calculatre means on numbers

Answer 1

To find the mean of n numbers, we divide the sum of the n numbers by n.

If we let n = 29, we can work backwards to find the sum of these test scores.

Multiplying the mean by the 29 we get: 77.8 x 29 = 2,256.2

Answer 2

The 'mean' is the average - the mid-point of all the numbers you are looking at so, for example the mean of:

2 and 4 = (2+4)/2= 3
(divide by 2 because there are two numbers)

4 and 6 = (4+6)/2= 5
(divide by 2 because there are two numbers)

2 and 4 and 6 = (2+4+6)/3= 4
(divide by 3 because there are three numbers)

10 and 14 and 16 and 22 = (10+14+16+22)/4= 15.5
(divide by 4 because there are four numbers)

Answer 3

It means the average value for a set of numbers. To find the mean, you add the numbers then divide by the frequency or amount of numbers in the set. For example:

{1, 2, 3, 4, 5 } = 15 / 5 = 3 so three is the mean of that set or

{10, 10, 10} = 30/3 = 10 so 10 is the mean or average value. Hope this helps.

Answer 4

in Statistics this is the simple average, where you divide the sum of a given set of numbers by the numbers of given numbers.
Example:
the Mean of 2,6,5,9,3,7 is their sum / 5 (there are 5 numbers)
(2+6+5+9+3+7)/5 = 32/5

Answer 5

"maths" - that would be great britain
but the mean is the same
simply the average of the numbers
add the numbers and divide the total by the number of numbers
don't confuse with the median, which is the number in the center of all the numbers lined up

Answer 6

mean- the average

for example: 4,6,7,7
4+6+7+7=24
24 divided by 4 (because there are four numbers)
=6 (the average)

Answer 7

mean is the average of all added number divide by the number in sequence /// 10, 10, 10 would be 30 divided by 3

Answer 8

OK! so i'm no math whizz, at least i got the word 'average' in my answer

Answer 9

Averages.
