Mean: 20.2222222 Median: 12 Mode: 11 Range: 79
That set has no mode.
These are your 5 numbers: X X X X X the median (the middle number of a row) is 11, that means: X X 11 X X the mode (the most frequent number in a row) is 12, that means: X X 11 12 12 the mean (the average) is 10, that means: (X+X+11+12+12)/5=10 or: X+X+11+12+12=50 or: X+X=50-12-12-11 or: X+X=15 so the remaining numbers must be 15 combined, and lower then 11, that means they can be: 5 and 10 6 and 9 7 and 8 so you have 3 possible solutions: 5 10 11 12 12 6 9 11 12 12 7 8 11 12 12
One possible set is {9, 9, 10, 11, 12, 15, 18}
The mean is the average. For example if you had the numbers 11, 10, 12, 11, 7, and 15. You would add them up and divide by how many numbers there are (which in this case is 6). The number you get is your mean (in this case the means in 11).The mode is the number that occurs most often. Using the same set of numbers above (11, 10, 12, 11, 7, and 15), the mode would be 11 because that's the only number that occurs the most. In other words, there is more than one of the same number.
10 = x 11 = xi 12 = xii
8
9, 10, 11, 12
Mean = 14 Median = 12 Mode = 12
mean = 19 median = 12 mode = 12
All of the numbers appear once and as a mode is the most commonly occurring number, there is no mode.
You can select 12 numbers for the first digit, 11 numbers for the second digit, and 10 numbers for the third digit; so 12*11*10 = 1320 sets of 3 numbers can be made out of 12 different numbers.
