Question

2. What association would you expect if graphing height and weight? (1 point)

positive

nonlinear

negative

none of these

Answer 1

Okay so we're talking about graphs.

Let's pretend that HEIGHT is on the X AXIS,
and WEIGHT is on the Y AXIS.

I'll explain each of the answers for you,
and you will choose the one that seems to make the most sense,
okay?

~~~~~~~~~~~~~~

A POSITIVE association means that....

if HEIGHT INCREASES,
WEIGHT also INCREASES.

~~~~~~~~~~~~~~~~~

A NON-LINEAR association means that....

HEIGHT and WEIGHT are totally UNAFFECTED by one another,
and they are totally UNRELATED.

~~~~~~~~~~~~~~~~~~

A NEGATIVE association means that....

If HEIGHT INCREASES,
then WEIGHT DECREASES.

~~~~~~~~~~~~~~~~

Now,
which one makes the most sense?

You can take a look at these graphs too:

Answer 2

Oh, by the way,
this isn't exactly a Language & Culture question.

Next time, try asking in one of the science sections,
like biology, chemistry, or physics.
Even psychology.

You'll get an answer sooner, that way.
