Question

1. suppose the results of a recent study found that there is a positive correlation between the number of friends a college student has and the number of illnesses he or she experiences. the best interpretation of this correlation is that

when students friends are negative, they are more likely to experience illness

the more friends a student has, the more likely he or she is to become ill through the spread of infectious viruses

the more friends a student has, the fewer illnesses he/she experience

there is no relationship between the number of friends a student has and the number of illnesses he or she will experience

1. in this type of study, the researcher tries to intervene as little as possible

ideally, the participant does not even know that he or she is being observed

naturalistic observation

survey

experiment

cross - sectional study

Explanation:

For question 4: Positive correlation means as one variable increases, the other tends to increase. Option B aligns with this by linking more friends to higher illness likelihood via virus spread.
For question 5: Naturalistic observation involves minimal researcher intervention and unobserved participants, matching the description.

Answer:

1. B. the more friends a student has, the more likely he or she is to become ill through the spread of infectious viruses
2. A. naturalistic observation
