Answer: the first one is the answer I think
Step-by-step explanation:
Answer:
The mean absolute value is 7.7, when rounded to the nearest tenth.
Step-by-step explanation:
1.) To get the mean absolute deviation you have to find the mean first:
- 32 + 35 + 20 + 16 + 28 + 13 = 144 ÷ 6 = 24
2.) Then, you have to find the difference of each element in your data set that is away from the mean. Then, you have to find the absolute values of the answers:
- 32 - 24 = | 8 | → 8
- 35 - 24 = | 11 | → 11
- 20 - 24 = | -4 | → 4
- 16 - 24 = | -8 | → 8
- 28 - 24 = | 4 | → 4
- 13 - 24 = | -11 | → 11
3.) Then, you have to find the mean of the absolute values:
- 8 + 11 + 4 + 8 + 4 + 11 = 46 ÷ 6 = 7.6666666666666666666666666666667 = 7.7
