Aresearcher measures iq and weight for a group of college students. what kind of correlation is likely to be obtained for these two variables?
a) a positive correlation
b) a negative correlation
c) a correlation near zero*
d) a correlation near one

Option b

Step-by-step explanation:

Given that a  researcher measures IQ and weight for a group of college students.

In general, we think that the weight has nothing to do with IQ of a person and hence not correlated.

But if we go deep, we find that after a certain weight, the person becomes lazy and inactive with a chance to have reduced IQ

Weight gain causes also health problems including less activity of both brain and body and hence there is a chance for less IQ

So we find that as weight increases iq decreases and when weight decreases, IQ increases.

Thus we can say that there is a negative correlation but not necessarily near to one.

Hence option b is right

the answer is d. 75%

c

step-by-step explanation:

i think because what else can be a sample of every member
