We are looking for someone to do the statistical analysis and its interpretation for our research. We have a data base spanning 20 years (1998-2018) with certain data points, with which we want to answer 2 primary questions and about 5 secondary questions. You would be asked to look at our data base and determine which tests are applicable (and since we want to be as thorough as possible, we would want all applicable tests run, not just the most applicable). You would then actually run these tests in SPSS and interpret the results to see what it suggests about our questions. We would ask you to share the results, a description of the process, and your SPSS workbook. We are asking this because we are not very practiced at data analysis and, while we understand something once we've seen it, we don't necessarily know how to do it ourselves. Seeing as this is a research project we are still working on, there is a chance we ask for the opportunity of one or two revisions (they would not be major points, probably the inclusion or exclusion of data). Since our data spans 20 years and ends in 2018, we would also ask you to make sure your analysis takes into account that the follow-up between people differs. This is a major point upon which we insist. While we know this is important, we're not quite sure how to do it ourselves. PS. both of our primary questions deal categorical variables. Our secondary questions deal with continuous variables.
