Answer:
The mean of Sample #2 is 8
The mean absolute deviation for Sample #2 is 4.08
Step-by-step explanation:
To find the mean for Sample #2, you find the sum of the values in the set and divide it by the number of elements in that set.
18+14+0+7+5+7+10+7+6+9+12+3+14+4+11+6+0+10+9+5+0+16+11+2+4 = 200
200 ÷ 25 = 8
To find the mean absolute deviation for Sample #2, you calculate how far away each data point is from the mean using positive distances. These are the absolute deviations. Afterward, you add those deviations together and divide the sum by the number of data points.
10+6+8+1+3+1+2+1+2+1+4+5+6+4+3+2+8+2+1+3+8+8+3+6+4 = 102
102 ÷ 25 = 4.08
