Question

Please help! Will give fan and medal.

Identify the outlier in the data set. Then find the mean, median, and mode of the data set when the outlier is included and when it is not.
188 226 113 372 87 53 127 9 199 102 176 231 142 215

Thank you in advance :)

Answer 1

first but the data in order from smallest to largest

Answer 2

not but, put the data in order

Answer 3

Okay.

9 53 87 113 102 127 142 176 188 199 215 226 231 372

Answer 4

grab a calculator, add up all the data sets and then divide the SUM by the Number of data sets

Answer 5

for your mean

Answer 6

next will move on to MODE

Answer 7

Data will be ordered into: 9, 53, 87, 102, 113, 127, 142, 176, 188, 199, 215, 226, 231, 372

If it is only asking for one outlier, I would predict 372 being the outlier.

If 372 is included:
Mean- 160
Median- 159
Mode- All numbers appear once unless I did not read correctly, there should not be a mode/all numbers are the mode

If 372 is not included:
Mean- 143.69
Median- 142
Mode - All numbers appear once unless I did not read correctly, there should not be a mode/all numbers are the mode

Answer 8

So sorry for the late reply. So for the mean I got 2240. Then I divided (by 14) like you said and got 160. What next? @latinC

Answer 9

Mode = the most repeated number in the data set, which I didn't see any repeated numbers, so MODE = NONE

Answer 10

Alrighty.

Answer 11

median is the always the number in the center of the data set, if the data set is even like this one then you'll gave to add the inner most number and divide by 2

Answer 12

Thank you so so much for all your hard work @Scooby6363 , you're awesome :) however, I do want to learn how to do this. So I'm going to keep working with LatinC. Thank you for your time and effort though!!!! I fanned you. :)

Answer 13

Okay.

Answer 14

(142+176)/2 should give you your median

Answer 15

so we have mean, median and mode right

Answer 16

Is 228 the correct answer for Median?

Answer 17

No :( your median when averaged out should always be between the two inner numbers

Answer 18

159?

Answer 19

it's like finding the mean of the two numbers, and YEs 159

Answer 20

we have mean, median, and mode right

Answer 21

Okay. Also, it's also asking for the mean, median, and mode if the outlier is NOT included. What do I do then?

Answer 22

Yes, we have the mean, median, and mode.

Answer 23

If, Opps

Answer 24

okay,

Answer 25

outlier is always going to at one end, its the data set that sick out the most from the rest.
in other words the difference from an outlier will be much higher than any other data set

Answer 26

Ahh, okay.

Answer 27

so in this set you definitely have one

Answer 28

Alrighty

Answer 29

did you get 372

Answer 30

Yes! Sorry lol I meant to type that :) thank you for all your work.
