Question

Find the Mean, Median, Mode, and Range of the following data:

6, 9, 3, 18, 25, 7, 6, 11, 5

Answer 1

Mean: is the avg of your data:
\[ \large \bar{x}=\frac{1}{n}\sum_{i=1}^nx_i\] where \(x_i\) is each data point, and \(n\) is the number of data points you have (here you have 9 data points, so \(n=9\).

Mode: is the most frequently occurring data point (which one appears the most often)

Range: is the difference between the largest value in your data minus the smallest value
range = \(\large x_{\text{largest}} -x_{\text{smallest}}\)

Answer 2

Oops I forgot the median.. the median is the middle of your data once you order it from smallest to largest. So your data set when re-ordered is:
3, 5, 6, 6, 7, 9, 11, 18, 25

If the number of data points is odd, take the middle value from the set

If the number of data points is even, take the TWO middle points, and take their mean.

Answer 3

the median is 25 mode is 6 mean is 10 range is 25,18,11,9,6,5,3 those are your answers :)

Answer 4

the median is certainly not 25

Answer 5

When you find the median, you must sort your data from smallest to largest. Otherwise the median of a data set would not be unique

Answer 6

yes it is

Answer 7

median is in tha middle im not stupid!

Answer 8

but it's the middle in a SORTED list

Answer 9

Even here they tell you so: http://www.mathsisfun.com/definitions/median.html

Answer 10

DUHHHHH ITS THE MIDDLE NUMBER DUDE

Answer 11

u callin me a liar?

Answer 12

Same thing with the range.. you don't take the last - first value... you take the LARGEST - SMALLEST value

Answer 13

guys calm down

Answer 14

It's the middle number when you SORRTTTTTTTTTT the data set

Answer 15

THATS THE MEAN

Answer 16

NOT THE MEDIAN

Answer 17

No it is not!! Where on Earth did you learn this?

Answer 18

fine go with what u think ok? goodbye bro

Answer 19

Please go read this: http://www.purplemath.com/modules/meanmode.htm

Answer 20

It's not what I think, it's fact.

Answer 21

so what Happie is not right?

Answer 22

Yes unfortunately they are incorrect. You can google the median all you want, and you see that you must re-order the data from smallest to largest, and then find the middle value in that sorted list.

Answer 23

just go with what u kirby if u want then just... im done

Answer 24

k kirby than whats the right answer

Answer 25

\[\text{mean}=\bar{x}=\frac{1}{9}(6+9+ 3+ 18+ 25+ 7+ 6+ 11+ 5)\]
mode = 6

median: re-sort your data to give:
3, 5, 6, 6, 7, 9, 11, 18, 25... and take the middle value 7

range: largest - smallest value = 25 - 3 = 22
