Can you help?
IDUT=I Don't Understand This
the first thing to help us out is to order it, and how do we determine the value of a mean and median?
we add all the numbers up?
also, consider that outliers affect the mean .... so 2 options are just not valid to start with
adding up, and dividing is how we find the mean and just picking the number i the middle of an ordered set is how we can determine the median
IDK what the middle # is.
what does the ordered set look like?
first off, is the mean going to be affected? lets narrow our options
ok im back
NO DIRECT ANSWERS
I always say that when I put a board DON'T YALL FOLLOW DIRECTIONS?
focus on the question, not on the spam :)
it didnt say ....
will 42 affect the mean?
it should yes. so that narrows our options
so the question is really, how does it affect the median. wht is our ordered set?
in elementary school grades they teach you how to determine if one number is bigger or smaller than another. .... just order the numbers from smallest to biggest.
11 , 12 , 13 , 14 , 14 , 16 , 19 , 21
good, now we can find the middle
yep, now adding on the 42, what does the middle become? 11 , 12 , 13 , 14 , 14 , 16 , 19 , 21, 42
11 , 12 , 13 , 14 , 14 , 16 , 19 , 21, 42 >>>>>>>>>>< <<<<<<<<<< yep, still 14 so the median doesnt change, but the mean does
So my answer is D
lets read them A. The mean and median are not affected. ^^^^^ ^^^^^^^^^ false B. The mean and median both increase by 3. ^^^^^^^^^^^ false C. The mean increases by 3, but the median stays the same. ^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^ true enough D. The median increases by 3, but the mean stays the same. ^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^ false
oops that was what I meant
I meant to say C
TY for the help
