Answer 5

Aw, and I was gonna help you with A.

Answer 6

Do you know what an Outlier is?

Answer 7

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

Answer 8

an observation point that is distant from other observations.[1][2] An outlier may be due to variability in the measurement or it may indicate experiment

Answer 9

B and C are basically the same, right?
Or am I just seeing lag? :/

Answer 10

B is with outlier, C is no outlier @jabez177

Answer 11

yes what he said

Answer 12

Basically B is finding the mean of ALL NUMBERS,
C is taking the outlier value OUT. Then calculating the mean.

Answer 13

Outlier is a number in a set of data that is either way smaller or way bigger than most of the data. Find out what "outlier" means in math with help from an experienced mathematics educator in this free video clip. https://www.youtube.com/watch?v=D0QdVzcWCGs

Answer 14

So the outlier is the BIGGEST number or the SMALLEST number FARTHEST away from the data set.

Say for example I have numbers 1, 3, 5, 4, 6, 20, and2

Answer 15

Um, I think he found the outlier already

Answer 16

yea the outlier is 28

Answer 17

20 is the outlier because it is FARTHEST away from the set. All the other numbers are within the range of the data set.

Answer 18

Ohhh!!!
Sorry...

Answer 19

Mean is the average.
So we add all the numbers in the set, then divide it by how many numbers there are. :)

Answer 20

"B. what is the mean of the data WITH the outlier included.
C. what is the mean of the data WITHOUT the outlier included"

Answer 21

So in B. it is asking what is the average with the outlier.
So we add all the numbers, including 28

Answer 22

theres 11 numbers

Answer 23

68+63+67+ 66 +65+ 87+ 69+ 61+ 86+ 82+ 28 = what?

Answer 24

mean formula:\[\frac{\text{Add all the values together}}{\text{Number of values in the set}}\]

Answer 25

What is the sum of all those numbers? :) Add them up.
You may use a calculator.

Answer 26

742

Answer 27

Now how many numbers are there?

11, right?
So we divide 742 by 11

Answer 28

dont know if this seems right 67.45454

Answer 29

Mean values can be decimals.

Answer 30

Right on! :)

Answer 31

So for B, what is the answer?

Answer 32

what is the mean without the outlier ?

Answer 33

Take the 28 out

Answer 34

And calculate the mean of the rest

Answer 35

Add the numbers together except the 28

Answer 36

714

Answer 37

Now divide it by 10 since we did not add the 28 in there so there are only 10 numbers.
Divide 714 by 10

Answer 38

71.4

Answer 39

And that is your mean without the outlier. :)
