Hi,
ReplyDeleteI got one question in this chapter.
Please refer to the following question:
Give the sample 14,14,5,5,-19,5, add one more sample value that will not change the mode nor the range.
According to the solution, the correct answer is -14.
I understand that the mode is 5.
And the range should be between 14 and -19.
I just wondering that except 14, every number between 14 and -19 could be the correct answer to be the added value in this set.
So I was a little confused about the answer.
Could you give me some instruction about this problem?
Thank you very much,
Elsa
I believe that given the way the question is written they only want you to choose from values already in the sample. That said, I don't understand why 5 and -19 aren't both answers. I'm out of the office now. Will look when I return to see if I can give more info.
