Question

Stats (SD) help

Answer 1

On a given math test with a maximum possible score of 100 points, the vast majority of the 149 students either scored perfectly or made a zero. One student was within 5 points of the mean.

Is the mean of the dataset equal to the median?

Answer 2

Or could it be?

Answer 3

Here is the explanation of the book

"It could be because the one student within 5 points of the mean could have a score equal to the mean and of the remaining 148 student, half could score 0 and the other half could score 100 (perfect score).

BUT I THOUGHT THE PROBLEM SAID THE DUDE SCORED WITHIN 5 POINTS OF THE MEDIAN, NOT THE EXACT MEAN!!!!

Answer 4

It also says if the numbers were unequal than it would not equal the median.

Answer 5

"It could be because the one student within 5 points of the mean could have a score equal to the mean"

Yeah that makes zero sense lol, unless they just means he's anywhere in a range of plus or minus 5 points from the mean... which would mean he could have scored exactly the mean.

Answer 6

I'm sorry. I did not realize agent answered this.

Answer 7

@agent0smith thank you very much. I was going nuts over this.
