Could you please read this article and answer these questions?
1- What are the next steps you would like to see for a follow up experiment? What else would you test? This experiment focused on finding a correlation between loneliness and immune responses. What type of experiment would need to be conducted to show a causal relationship between loneliness and immune response?
2- Compare table 1 to figure 1. Why do you believe the researchers chose to only graph the effect of loneliness on immune response?
3- What are the gray and black circles in figure 1 displaying? In your response, be sure to discuss the immune response and the loneliness score.
4- What does double blind mean? What does within-subject mean? Why is this a good design?
5- Provide a list of factors that were tested in this study. How might these aid the researchers in discovering a link between the immune system and loneliness? Why might the researchers focus on the potential confounders?
