Which bivariate association(s) would be best represented using a scatterplot?

We are interested in exploring the association between income and happiness, separately for male and female participants. The two scatterplots below show the association between these variables, conditioned on whether or not participants are male or female. Use the information in these figures to respond to the prompt below: In a short paragraph, describe the associations that are represented in the scatterplot(s). Be sure to discuss the following: 1) The strength and direction of the associations (2 pts), 2) the dependent and independent variable in the associations (1 pt), 3) which association is stronger (1 pt), and 4) a final sentence bringing together all of this information to summarize what the association looks like across these groups (2 pts).

When assessing the variability of a measure, which of the following statistics would be appropriate to use? 

True/False: If data have extreme skewness or other non-normality, it is possible that the IQR is greater than the range. 

A 76-year-old man is admitted to the emergency department with right-sided weakness and difficulty speaking.  Within an hour, his symptoms have subsided, and he is admitted with a diagnosis of transient ischemic attack (TIA).  The client asks, “What is a TIA?”  What is the best response by the nurse?
