Answer:
mean for a = 60/10 = 6
mad of a = 2
mean for b = 80/10 = 8
mad of b = 2
Step-by-step explanation:
Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set. The mean absolute deviation, MAD, is 2.
\frac {1}{n} \sum \limits_{i=1}^n |x_i-m(X)|
m(X) = average value of the data set
n = number of data values
x_i = data values in the set
mean = average.
what? um child.... anyways
Answer:
it 24 on all side together
Step-by-step explanation:
6+6+6+6
yhe other one is 8
2+2+2+2
The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)
<h3>Fraction</h3>
Her calculation:
- 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)
- 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)
- 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8
- 14 and StartFraction 5 over 8 EndFraction: 14 5/8
Her error was multiplying 7 by 2 and adding with 5/8(step 3)
Correct calculation:
7(2 + 5/8)
= 14 + 35/8
= (112+35) /8
= 147/8
= 18 3/8
