Mean absolute deviation means mean of the absolute deviation around mean
so, first we calculate the mean
Mean= sum of all observations/total number of observations
= (63+70+68+73+58+67)/6
=66.5
Absolute deviations around mean:
|63-66.5|=3.5
|70-66.5|=3.5
|68-66.5|=1.5
|73-66.5|=6.5
|58-66.5|=8.5
|67-66.5|=0.5
Mean of absolute deviation around mean=(3.5+3.5+1.5+6.5+8.5+0.5)/6
= 4
Hence, mean absolute deviation is:
4
Answer:
70
40 % of 70 is 28
Step-by-step explanation:
5 | 0 3 6 | 5 4 7 | 5 7 8 8 | 2 4 5 6 7 7 9 | 0 1 2 3 4 6 7 9 5 | 0 = 50 49 85 86 ' is not a valid one
