Robert is using the following data samples to make a claim about the house values in his neighborhood:

House Value
A $250,000
B $275,000
C $300,000
D $267,000
E $250,000

Based on the data, should Robert use the mean or the median to make an inference about the house values in his neighborhood?
He should use the mean because it is in the center of the data.
He should use the median because it is in the center of the data.
He should use the median because there is an outlier that affects the mean.
He should use the mean because there are no outliers that affect the mean.

hint: are there any outliers?

unchartedid1023 · Answer

I'm sorry, I don't know a lot about outliers and this! This question is apart of a pretest, something I get before I learn the assignment, and I just wanted to understand the question. I literally understand NOTHING of this question!

vocaloid · Answer

ok, no problem ^^

vocaloid · Answer

an outlier is a data value that is much much higher or lower than the others

unchartedid1023 · Answer

Oh ok

vocaloid · Answer

the data values in your problem don't look like they have any outliers, since they're within about a 250K to 300K range

unchartedid1023 · Answer

300,000, right?

sammixboo · Answer

Since it is a pre-test, you should just do what you can so you see what you know before you continue onto your module/unit. You aren't supposed to know everything on the pre-test :)

unchartedid1023 · Answer

Oh ok nevermind xD

sammixboo · Answer

But it is good to learn early as well, so it's your choice!

vocaloid · Answer

I wouldn't consider 300,000 an outlier in this case

unchartedid1023 · Answer

Ok Vocaloid

vocaloid · Answer

(there's actually a formula to determine whether something is an outlier or not, but you'll learn that later)

vocaloid · Answer

so; if there are no outliers, we use the mean

unchartedid1023 · Answer
