See??leading to a where the reports are collected. Stat with _How to find reports.pdf in that folder, which includes some links to material not found in the Drive folder itself. In 2015-16, I recruited a number of fellow hikers with analytic and data presentation skills to do a comprehensive reporting on the 2015 survey, which had 1,286 useful respondents. See, most notably,? BTW: I'd love other volunteers with data skills I lack -- data presentation skills, particularly in Tableau, analytic skills using tools like R. Non-linear modelling is, in particular, a skill set that I would like to recruit. Email me if interested It was a ton of work and it wasn't clear that repeating that work each year was worth the effort. And I feared burnout among the volunteers I needed to present the data well. I decided to efficiently use my own resources, and to readily recruit others with analytic skills, by waiting until I could pool results across multiple years. That would allow us to look both at problems that were the same year-to-year and how some problems differed between years. There are some reports from 2016 thru 2019, but they are minimal compared to the 2015 reporting. There are also a number of 2014 reports in the Drive folder. So I am working now on cleaning the data from 2016 to 2021 (e.g. addressing outliers and internally inconsistent responses). I'll then work on pooling 2014 and 2015 with the later surveys, which should give us 6,000 data points on many issues.? Serious pooled reports probably won't come out until the Spring as the data cleaning work is surprisingly tedious and I don't give the data to folks with analytic skills until it is reliable.? There is an academic group of Wilderness Medical Society members out of UCF Fresno, led by Dr. Susanne Spano, have published peer-reviewed reports on the earliest (2014) version of the survey and I look forward to seeing their analysis of the pooled data.?
