Answer:2.1
Step-by-step explanation:
To find the mean absolute deviation,
find the mean
find the difference between each data value and the mean
take the absolute value of each difference
find the mean of these differences
{2, 2, 5, 7, 10, 10}
Number of values = 10
Sum of values = 2+2+5+7+10+10= 36
Average = 36/10 = 3.6
Deviation from the mean =
Deviation. Absolute value
2-3.6 = -1.6. 1.6
2-3.6 =-1.6. 1.6
5-3.6=1.4. 1.4
7-3.6 =3.4 3.4
10-3.6 =6.4. 6.4
10-3.6 =6.4. 6.4
Sum of absolute values= 1.6 + 1.6+1.4++3.4+6.4+6.4= 20.8
mean absolute deviation
=20.8/10= 2.08
= 2.1 to the nearest tenth
