Question

A student wonders if people of similar heights tend to date each other. She measures herself, her dormitory roommate, and the women in the adjoining rooms; then she measures the next man each woman dates. Here are the data (heights in inches):
Women 66 64 66 65 70 65
Men 72 68 70 68 74 69

Answer 1

Which of the following statements is true?
A. The variables measured are all categorical.
B. There is a strong positive correlation between the heights of men and women since the women are always smaller than the men they date.
C. There is a positive correlation between the heights of men and women.
D. Correlation makes no sense here since gender is a categorical variable.


Imo C

Answer 2

Answer 3

Hmm, looks like a toss up between positive correlation and strong positive correlation.
I'll plot it out and take a look.

Answer 4

I don't say strong because some share the same value i.e., 65 and 66 :)

Answer 5

Eh, .. it's still pretty strong-looking. I'm getting a correlation coefficient, r = 0.9132

Answer 6

There is a strong positive correlation between the heights of men and women since the women are always smaller than the men they date.

Answer 7

What's this since business though?

Answer 8

Meeeeeehhhhhh

Answer 9

Yeah, that part bothers me too...

Answer 10

That's not really the reason... but yeah.....

Answer 11

This is stupid all the time LOL.

Answer 12

@CliffSedge would it be safe to go with C then?

Answer 13

Yeah, I think C is safe. That reason given smells pretty bogus.

Answer 14

I'd argue it in any case.... LOL... Next Q!!!! http://openstudy.com/study#/updates/506f933ce4b060a360ffc1ab
