5, 5, 9, 12, 18, 22, 25The median is 12.
16 18 22 28 The median (middle number when numbers are in numerical order) is 20.
Median of 16 and 28 is (16+28)/2 = 22

The mean, median, and mode of a normal distribution are equal; in this case, 22. The standard deviation has no bearing on this question.

The Median is 23.5.
In the example provided, the quartiles are: 25% = 16.5 (the median of {15, 16, 17, 18}) 50% = 18.5 (the median of {15, 16, 17, 18, 19, 20, 21, 22}) 75% = 20.5 (the median of (19, 20, 21, 22})

It is 18, the middle number when they are in order.
I believe it is 19.5.
I'm guessing you mean the median. The median is when you put all the numbers given in a set in order, for example: 20, 21, 22, 23, 24. The median is the number in the middle of the set, which would be 22 in this example. If you have two numbers in the middle, find the average of the two numbers, and that's your median!
