The imply deviation or absolute deviation is calculated via the summation of the distinction of every fee from imply. The system used by the calculations of MAD is as follows:
$$ MAD = Σ|xi - m| / n $$
wherein,
xi are the person values
m is the mean of numbers
n is the whole wide variety
The system for the calculation is discussed earlier, here we have an instance:
Instance:
Calculate the suggest absolute deviation for the facts set: 4, 16, 8, 9, 14, 5?
Answer:
Step No. 1:
The formula is:
$$ MAD = Σ|xi - m| / n $$
Here,
Step No. 2:
Find the mean:
\(m = 4 + 16 + 8 + 9 + 14 + 5 / 6 \)
\(m = 56 / 6 \)
\(m = 9.33 \)
Step No. 3:
find deviation from the mean:
\(4 – 9.33 = -5.33 \)
\(16 – 9.33 = 6.67\)
\(8 – 9.33 = -1.33 \)
\(9 – 9.33 = -0.33 \)
\(14 – 9.33 = 4.67\)
\(5 – 9.33 = -4.33 \)
Step No. 4:
determine the mode of each cost:
\(|-5.33| = 5.33\)
\( |6.67| = 6.67 \)
\(|-1.33|= 1.33\)
\(|-0.33| = 0.33\)
\(|4.67| = 4.67\)
\( |-4.33| = 4.33 \)
Step No. 5:
decide the mean of absolute values:
\( m = 5.33 + 6.67 + 1.33 + 0.33 + 4.67 + 4.33 / 6 \)
\( m = 22.66 / 6 \)
\( m = 3.8 \)
additionally, our suggest deviation calculator makes use of this components for the calculation of the MAD. For ease, you could additionally attempt our on line mean mode median calculator that lets you calculate the mean, mode & median of your given information set.
