I'm really hoping you're better!
Recovery is ongoing here:-)
Given the literature review and your initial interests, what variable are we looking at?
I guess I really need to know which research question you think would be the easiest.
Are you still planning on using the WHO stats?
I was thinking we could examine the countries in the lit review. Bangladesh, Egypt, Uganda, Colombia, Pakistan and the US. We could include Korea, too, since you researched that.
However, I do not know if you are considering the intentional and unintentional injuries as the variables. I would expect to see differences in types of injuries and a gender-based difference, as well. Unfortunately, I do not recall whether the WHO stats contain gender.
I realize you mentioned policy differences and in some cases the abject lack thereof. One could also make the case for challenges implementation of childhood injury prevention poses. Of course, to some extent, children and adolescents will also take risks. That is of course their nature and how they discover the world.
At any rate, if you can clarify your thoughts as to the research question you seek to answer through the data analysis, I should be able to help with this part.
This, too, will inform your question for the stats experts. I will try to discover which one is familiar with this type of project. Hope that helps!
