Which of the following statements about correlations is correct?

a. Wynne hypothesized that the likelihood of buying organic products would be related to tendency to use public transport. Wynne found a positive correlation, but unfortunately, Wynne did not think of measuring the attitudes about the environment, which drives both of these behaviors. This is a confounded relationship.

b. Sally collected data on risky behaviors, personality traits and several demographic variables. She noticed a moderately strong positive correlation between the likelihood of engaging in risky behaviors and the number of pets someone owns. She had no theoretical reason to think that these variables are related. This is an example of spurious correlation.

c. John is interested in the relationship between political identity and age in the UK. Higher scores on political identity questionnaire means more the person identified as being more liberal. Lower scores indicate that the person identifies as being more conservative. John observed a weak-moderate negative correlation. Upon further inspection, she realized that this relationship is much stronger in people who identify as Caucasian. The relationship is weaker in the people who identify as a racial minority. This is an example of a moderated relationship.

d. Heather hypothesized that people who spend a lot of time on social media platforms tend to have lower overall life satisfaction. She thinks that this is because social media only shows the best parts of someone's life, which results in comparison, and these comparison leads to lower life satisfaction. This is a mediated relationship.
