10. Identify whether each scatterplot is depicting a positive or negative correlation, or a zero correlation. A. B 11. Identify which correlation is strongest and which is weakest based on the scatterplots. A. 13 D 12. A researcher is interested in measuring participants' reaction time to seeing a motorcycle based on differing the lighting intensity on the motorcycles. The researcher has one condition where there is the standard lighting, and two other conditions with enhanced lighting intensity. What is the IV and DV? 13. A researcher has one group of participants look at pictures of nature, whereas the other group looks at pictures of a city scene before taking a cognitive test. They want to determine whether participants perform better on a cognitive test after looking at a picture of nature as opposed to a city scene. What is the IV and DV? 14. Which is a stronger correlation coefficient (Person r), -.45 or +.44 and how do you know? What does a correlation of +/- 1.00 mean
