Question

ℍ𝔼𝕃ℙ ℙ𝕃𝔼𝔸𝕊𝔼 𝕄𝔼𝔻𝔸𝕃 𝔸ℕ𝔻 𝔽𝔸ℕ

Answer 1

The following data show the height, in inches, of 11 different garden gnomes:

2

9

1

23

3

7

10

2

10

9

7



After removing the outlier, what does the mean absolute deviation of this data set represent? (4 points)


On average, the height of a garden gnome varies 3.2 inches from the mean of 7 inches.

On average, the height of a garden gnome varies 3.6 inches from the mean of 6 inches.

Answer 3

\(\large{\text{outlier}}\): a number outside the range of the rest,
example:\[1,8,15,23,58\]58 would be the outlier in this set.

\(\large{\text{average}}\): add all the values up and divide by the number of values,
example, using previous example set:\[\frac{1+8+15+23+58}{5}\]because there are 5 values in that set.

Answer 4

21

Answer 5

The stuff I just posted was an example to help you understand.
Where did you get a 21 from?

Answer 6

i added all the number then divided by 5

Answer 7

Just apply the same methods to the problem.

Answer 8

Ok then can you right the question?

Answer 9

then i can answer it please

Answer 10

You already posted the question though ? ._.

Answer 11

uhhmmmm i dont know

Answer 12

We're referring to the question you posted in the top of this thread right?

Answer 13

The correct answer is C. If you take the outlier 23 out of the equation and add all the numbers up you get 60. Divide it by 10 and you get 6. The height of the garden gnome is 3.2

Answer 14

7.54

Answer 15

7.54 from what?

Answer 16

@AceSpeedFighter the answer is not necessarily C.
\(\large{\text{Mean absolute deviation}}\) is the average deviation from the mean. This means you need to calculate the average, removing the \(\text{outlier}\) as I said, then find the difference between each number and the mean, before calculating the average of those differences.

Answer 17

@kittiwitti1 what would it be then im not to sure?

Answer 18

@kittiwitti1

Answer 19

Do you know how to calculate the mean (average)?

Answer 20

Add them up then divide by how many numbers there are

Answer 21

Yup.

Answer 22

thats what i got

Answer 23

7.54

Answer 24

The "mean absolute deviation" is when you take the average, then find how far away each value in the set is from the average.

After you find the differences, you have to find the average of \(those\) numbers, too.

Answer 25

I dont know i keep getting 7.54

Answer 26

Is your 7.54 value from my example or from the actual problem with the gnomes ?

Answer 27

ok...

Answer 28

Okay, we can do this over in another problem.
