Question

find the median,mode, and range for each set of number
12,5,9,18,22,25,5
median-
mode-
range-

Answer 1

median is "middle".  Put the numbers in order and find the middle number:
5, 5, 9, (12), 18, 22, 25
The median is 12.

mode is "most".  Which number appears the most in the data set:
(5), (5), 9, 12, 18, 22, 25
The mode is 5.

mean is the "average".  Find the sum and divide by the quantity.
 5 + 5 + 9 + 12 + 18 + 22 + 25 = 96 & there are 7 numbers in the data set:
96/7 = 13.7
The mean is 13.7

Answer 2

The median of the number series is 12, the mode of the given number series is 5, and the range of the given number series is 20.

Given :

Number  ---  12, 5, 9, 18, 22, 25, 5

First, arrange the given numbers in ascending order.

5, 5, 9, 12, 18, 22, 25    

The median of the given numbers is a middle number of the above number series.

5, 5, 9, (12), 18, 22, 25

So, the median of the number series is 12.

Mode is the number that obtains in the series most of the time.

So, the mode of the given number series is 5.

Now, the range is the difference between the highest value and the lowest value that is:

Range = 25 - 5

           = 20

So, the range of the given number series is 20.
