Answer:
Answer: 7.1
Step-by-step explanation:
Add up the values to find the mean of the data set:
25 + 28 + 30 + 32 + 35 + 41 + 54 = 245
Divide 245 by 7 because there are 7 numbers in the number set.
[tex]\frac{245}{7} = 35[/tex]
Subtract the numbers of the data set by the mean.
25 - 35 = -10
28 - 35 = -7
30 - 35 = -5
32 - 35 = -3
35 - 35 = 0
41 - 35 = 6
54 - 35 = 19
The mean deviation is always positive so change the negatives to positives. After that, add them up:
10 + 7 + 5 + 3 + 0 + 6 + 19 = 50
Then divide 50 by 7 because there are 7 numbers in the data set.
[tex]\frac{50}{7} = 7.14285714...[/tex]
Rounded the answer is 7.1
