So we have:
the mean; (a + b + c)/3 = 10 yield that a + b + c = 30 (numbers in order)
the range; c - a = 2 yield that c = a + 2
the median; b = 10.3
Substituting this information, we have:
a + 10.3 + a + 2 = 30
2a = 17.7
a = 17.7/2
a = 8.85 yield that c = 10.85
So the numbers are 8,85, 10.3, and 10.85.
Or,
since b = 10.3 yield that a + c = 19.7
a + c = 19.7
-a + c = 2 add both equations
2c = 21.7
c = 18.85 which yield a = 8.85
mean: 104.4 median: 104 mode: 104 range: 5
Mean = 98 Median = 97 Modes = 95, 96, 97, 99 and 103 To those who would argue that there is no mode, the number 98, for example, was observed 0 times. Consequently, these five numbers appeared more often than 98.
The median average of a set of numbers is the middle number when the numbers are listed in order. If there is an even number of numbers then the median is the mean average of the middle two. To find which is the median value add 1 to the number of items and divide by 2. If this is a whole number that is the median; otherwise the median is the mean average of the numbers that are at the whole part of this result and the next one: The dataset {95, 95, 98, 98, 98, 101, 102, 103, 104, 104} has 10 items, so the median is the mean average of the middle two. To find which is/are the median value::(10 + 1) /2 = 11/2 = 5.5 → the median is the mean average of the 5th and 6th items. → median = (98 + 101) ÷ 2 = 95.5
If you have at least two numbers than you always have a median. If the number of numbers is odd (e.g. you have the number 1, 3, 7, 9, 52), then the median is the middle number when arranged in numerical order (in this example median is 7. If the number of numbers is even (e.g. you have the numbers 1, 3, 7, 9, 52, 103), the the median is the average of the two middle numbers (in this case the average of 7 and 9 which is 8).
(103, 108, 117, 120) The mean is 112 There is no mode. The median is 112.5 (The mode is the number that is repeated most often in a list, but in this case they all appear only once.)

To put these in numerical order (for statistical purposes like the median) you would arrange it as: 103, Then you can manipulate it. For example, the median (middle number) is 102.5 (in this case both 102 and 103 are middle numbers so take the average of the two).
The median is 94.
There are an even number of numbers so you have to take the middle two and get the average of them. The middle 2 numbers are 108 and 110. Add them together and divide by 2 and you get 109.
They are: 1*103 = 103
