Can anyone help me answer this math question?

Anyone know this?

The data set shows the test scores for 7 students in a math class.

When calculating the average score for the class, the teacher claims that she should exclude Lee's test score because he was absent the entire week before the test.

Evaluate this claim by selecting the statement that best reflects why the reasoning is either correct or flawed.

Question options:
1) The reasoning is flawed. Lee's test score is not an outlier and removing it would decrease the mean.
2) The reasoning is correct. Lee's test score is an outlier and excluding it would increase the mean.
3) The reasoning is flawed. Lee's test score is an outlier, but there is no evidence that this test score is not typical.
4) The reasoning is correct. Lee's test score is not an outlier, but the value should not be included anyway due to the fact that he was absent.

Wow. -_- math sucks

(3) 10 char

It's definitely not 1. What does it mean by "outlier"?

 

[eyesofthekyuubi44]

I would say three for the first answer and two and four would be tied for second.

But go with three. I never took statistics in college though. I skipped it and went to the next one. Stats are hard. Good Luck.

im not good at math, but from a glance id say 2 but again could be wrong

 

[JackelLord]

I'm pretty sure it's No. 2

wait, It might be No.3 as well. hmmm.

A value that differs too much from the others.

OT: That's more interpretation than math itself. Lee's score does seem to be an outlier, but it might be due to the fact that he was absent, or not.

Number 3 seems to be the most likely to be correct. But that would depend on some satistics definitions. And I didn't take statistics yet. Sorry.

 

[kyubbi sagemode]

So I decided between 2 or 3?

 

[Sir Cool Blizzard]

Its 3 !! U_U

I would say 2. Regardless of Lee's previous scores, even if this score is around his typical score, the score would likely be effected due to his series of absences. Had he not been absent the score could have been much better, or possibly worse (though unlikely).

But to be honest we don't know enough information to give an actual answer. We don't know if the others students had been absent over the previous week. We don't know whether the information on the test was from information from the previous week either.

With the information we have here, from what I can tell Lee is an outlier (since he is clearly 22 points off from the next closest person, while everyone else doesn't have such a gap). This means that the answer is either 2 or 3, which confirm it to be an outlier. Of the two, I would pick answer 2, but it could very well be answer 3 as well.

At least this is how i see this.

Thank you guys! Can you help me with this other question?

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

1. The data is skewed to the bottom and contains one outlier.

2. The data is skewed to the top.

3. The data has a symmetrical distribution and contains no outliers.

4. The mean is most likely greater than the median.

Here's the link to the box plot

Definitely No.2

This ain't a math question it's a reasoning question. What the hell. Only a teacher should know this

 

[Hexuze]

You're not gunna learn sh*t if we keep telling you the answers. Do it yourself and if you mess up, learn from your mistakes. You little fker.

This. xD

3. Pretty sure that's an outlier.

Also does anyone else find it slightly racist that the Asian kid got the highest test score?
