Question

Hey. I really need help.
A teacher promised a movie day to the class that did better, on average, on their test. The box plot shows the results of the test:

Which class should get the reward, and why?

Answer 1

The 2nd period class should get the reward. They have the highest score, a perfect 100.

The 2nd period class should get the reward. They have a higher median.

The 4th period class should get the reward. Though the medians are the same, the first and third quartiles are higher, so the students did better on average than in the 2nd period class.

The 4th period class should get the reward. Their lowest score is an outlier, and should be thrown out.

Answer 10

\(\normalsize\cal\color{red}H\color{gold}e\color{greenyellow}l\color{lime}l\color{cyan}o\color{blue}!\) Look closer at the statistics of the 2nd period class. Are their scores higher than the 4th period class?

Answer 11

Yeah, but I am supposed to consider outliers and stuff... And I haven't gotten this one right yet...

Answer 12

Well, if you look at the medians, which period has a higher median?

Answer 13

Period two right?

Answer 14

Look reeeeeeally closely.

Answer 15

@Gabebro13 Are you supposed to consider the average score or the group with more students scoring higher?

Answer 16

@mrdoldum I am supposed to be considering outliers and data sets.
@Whitemonsterbunny17 I think they are the same actually.

Answer 17

@Gabebro13 yes, they are the same.

Answer 18

So you can rule out the first and second choices.

Answer 19

@Gabebro13 2nd period had less people who did better, but to have the same average those scoring above average had to have higher scores than those in the 4th period.

Answer 20

hmmmm. Okay I feel like D should be correct. Am I right?

Answer 21

???

Answer 22

@Gabebro13 Well, the average test score of each class is the same, so taking the question literally, neither class meets the requirements.

Answer 23

Yeah, but there is an outlier. So if you remove it, I guess the answer is D.

Answer 24

Sorry D: I was brbing ;-;

Answer 25

Lol @sammixboo

Answer 26

Oh i see thy question has been solved. T-T I must go then

Answer 27

@Gabebro13 So long as you know those are outliers. Depends on the style of box plot you have been working with.
