OpenStudy (anonymous):

When the outliers are removed, how does the mean change? dot plot with 1 on 18, 2 on 38, 1 on 40, 3 on 44, 1 on 46, 1 on 48 The mean decreases by 2.75. The mean increases by 2.75. The mean increases by 3.25. There are no outliers.

OpenStudy (anonymous):

I can post the picture of the table -- one sec

OpenStudy (anonymous):

OpenStudy (anonymous):

please, anyone? :c

OpenStudy (anonymous):

I believe it is 2.75 but I am not sure.

OpenStudy (daniee_bruhh):

"The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count." That is the definition of Mean.

OpenStudy (daniee_bruhh):

So Outliers are points or dots that are far away from a group of dots.

OpenStudy (daniee_bruhh):

That being said 18 is an outlier.

OpenStudy (anonymous):

does that mean that there is 9 total dots, correct?

OpenStudy (daniee_bruhh):

There are 8 dots because there was 9 but we have to get rid of the outlier.

OpenStudy (anonymous):

okay, okay

OpenStudy (anonymous):

so, now what do we do?

OpenStudy (daniee_bruhh):

We add them all up and then divide them by the number of points. In this case there are 8 sots and 5 points.

OpenStudy (anonymous):

so 8 / 5?

OpenStudy (daniee_bruhh):

Yup.

OpenStudy (anonymous):

but that is 1.6

OpenStudy (anonymous):

which isn't a option :o

OpenStudy (daniee_bruhh):

Hmm hold on.

OpenStudy (anonymous):

still here :)

OpenStudy (daniee_bruhh):

lol Yeah I know sorry about that.

OpenStudy (daniee_bruhh):

The thing is that I don't know what I'm doing wrong... Let me call a friend. @Dani_Rose

OpenStudy (anonymous):

thank you, dear :)

OpenStudy (daniee_bruhh):

OMG I KNOW HOW TO DO THIS I THINK LOL HOLD ON

OpenStudy (anonymous):

Okay, haha! thank you! take your time, really! :D

OpenStudy (daniee_bruhh):

Okay so the Total of numbers is 8. The sum of them is 342. If you divide that you get 42.75. Before with the outlier the sum was 360 and then divided it's 40. If we subtract 42,75 from 40 you get 2.75. It increased by 2.75 lol. So your answer is B love!

OpenStudy (anonymous):

okay thank you!! :D

OpenStudy (daniee_bruhh):

No Problem lol :D
