Question

Find the median,mode, and range for each set of number

Answer 1

5, 5, 9, 12, 18, 22, 25 put numbers in order least to greatest
25 -5 = 20 that is the range
12 is the middle number this is the median
5 is the mode, it is the number that is repeated the most

Answer 2

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
