First, you want to make it perfectly clear that you understand why the collection of data and eventual analysis is so vital to the overall health of the population that you will work with. It is vital that the community nurse assess the health needs of his or her community. Make sure to mention that conducting health needs assessments is important, that you are willing to get up to speed on the institution's approach to conducting them, and that you are always willing and ready to bring new ideas to the table. If you have direct experience in data analysis during your time as a nurse, be sure to talk about that experience, what you learned and what you can bring to work in this community nursing role.
