CHECK MY ANSWERS WILL MEDAL AND FAN

Answer 1

A student wants to report on the number of books her friends read each week. The collected data are below:


0

24

1

4

5

2

5

4



Which measure of center is most appropriate for this situation and what is its value?
Median; 2
Median; 4 This one
Mean; 2
Mean; 4

Answer 2

Which of the following is true of the data set represented by the box plot?

box plot with min at 10.5, Q1 at 11.5, median at 12.5, Q3 at 13.5, max at 15

The data contains at least one outlier.
The mean and median are most likely the same or very close. This one
The data is skewed to the right.
The median is 11.

Answer 3

Given the box plot, will the mean or the median provide a better description of the center?

box plot with min at 6, Q1 at 7.5, median at 8, Q3 at 23, max at 32.5

The mean, because the data distribution is symmetrical
The median, because the data distribution is symmetrical
The mean, because the data distribution is skewed to the right
The median, because the data distribution is skewed to the right THIS ONE

Answer 4

If the outliers are not included in the data set below, what is the mean of the data set?

42, 43, 46, 48, 57, 60, 96, 59, 38, 68, 29

47
48
49 THIS ONE
52

Answer 5

Thats all

Answer 6

That is a lot!

The first question I agree median is 4 Average = 3

Answer 7

Ya 4 questions lol ok do you know the other 3

Answer 8

The second one I disagree with your answer.

Answer 9

I am not that good with box plots, but if you look at the delta between quartiles. It is larger at the top. Right?

Answer 10

yes

Answer 11

Not the top they have it sideways so it is the right is skewed high

Answer 12

So I think it is the third option.

Answer 13

but look at the picture

Answer 14

I agree with your answer on the third question. The data is not symetrical.

Answer 15

ok

Answer 16

What is the picture for?

Answer 17

the second 1

Answer 18

Ok. Still three of the deltas were 1 10.5--- 11.5--- 12.5 --- 13.5 to 15 delta 1.5

Answer 19

ok yes

Answer 20

The last one ???

I messed up last time I did an outlier problem.

Can you define an outlier for me?

Answer 21

A value that is much larger or smaller than the others

Answer 22

And just to clarify the second question it the third option right?

Answer 23

That is what I think, but it is your decision.

Answer 24

ok and is the 4th one right?

Answer 25

I thought there was a way to quantify an outlier mathematically.

Like so many standard deviations from the mean or median ?

Answer 26

Yes using q1 and q3

Answer 27

I just don't know how to calculate the Q1 and Q3, sorry.

I need to learn more about box plots, since they were developed after I got out of college.

Answer 28

ok thank you

Answer 29

Your welcomed.

Answer 30

I will google it and see if I can figure it out.

Answer 31

ok

Answer 32

COOL. I found an on-line box-plot calculator. Entered the data and it said only the 96 was an outlier.

So the average without the outlier was your answer, 49.

Answer 33

ok thank you

Answer 34
