6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16
The average mean is: (11+12+13+14+15)/5 = 13
There are an infinite number of sets-of-4 that all have a mean of 12. Here are a few of them : 12, 12, 12, and 12 10, 11, 12, and 15 5, 10, 15, and 18 5, 7, 13, and 23 -12, 10, 20, and 30 1, 2, 3, and 42
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
Average = 12
Mean: 11.6 Median: 12 Mode: 10, 12, 15, 16, 5 Range: 11

If you have a plot with 5 10 15 13 and 12 the mean is where you add them all up 5+10+15+13+12=55 then, you divide by how many numbers there are in the plot 5 10 15 13 12 so divide by 5 then you have 11. do you get it?
6, 10, 11, 12, 14, 14, 15, 22 mean: 13 median: 13 mode: 14 range: 16
115/10 = 11.5
The mean absolute deviation is 2
The average mean is: (11+12+13+14+15)/5 = 13
There are an infinite number of sets-of-4 that all have a mean of 12. Here are a few of them : 12, 12, 12, and 12 10, 11, 12, and 15 5, 10, 15, and 18 5, 7, 13, and 23 -12, 10, 20, and 30 1, 2, 3, and 42
The mean is the sum of the values divided by the number of values. In this case (12+10+19+8+2+15+1+20+6+11+3+7)/12 = 9.5.
One possible set is {9, 9, 10, 11, 12, 15, 18}
Mean = (12+14+25+10+25+15+11)/7 = 112/7 = 16
The mean (average) of those numbers is 16.
