Question

10,10,10,10,8,8,8,8,8,12,12,11,Y.What is the median of this twelve numbers.

Can any body help me for solving this please???

Answer 1

Arrange the numbers in order (from least to greatest) and the two numbers in the middle are the ones you should add together (they'll have 5 numbers to each side of them). Once you've added them, divide them by two, and you'll have the mean.

Answer 2

Then what about ''Y''

Answer 3

i think the mean would still be the same one that you calculated, excluding the "Y".

Answer 4

sorry, I meant median, not mean.

Answer 5

I am sorry.I think its tricky.its from gre model question!!

Answer 6

then where should we put '' y'' in middle or side or....I don't know

Answer 7

I think either way your median would still be the same, but I'm not sure. Sorry.

Answer 8

Ok thanks for your time

Answer 9

Assume Y is 8, less than 8 or greater than 8 and calculate median for each case.

Answer 10

@ estudier Can you explain???

Answer 11

I thought I just did?

Answer 12

If Y is 8, what is the median?

Answer 13

It is 10

Answer 14

OK, I forgot to arrange them in order to start with

Where I said 8, use 10 instead.

Answer 15

So, if Y is 10, what is the median?

Answer 16

Again 10

Answer 17

If Y is 11, what is the median?

Answer 18

Oh ok again 10 ..thank you so much

Answer 19
