Done
Data Collection
- Closed out initial program advance in TEM.
- Created a number of database views to make survey data easier to process.
- Created 50 bar charts using R and LaTeX to describe distribution of answers to 50 survey questions.
- Calculated "course-grained" mean agreement of Parncutt sequences in both Parncutt et al. and in our survey. (Think Fleiss's Kappa with each fingering representing a category, 191 annotators, one example to classify, and no need to worry about chance agreement. Anyway, it made sense to me while I was doing it.)
- Split 191 complete responses into two datasets ("exploratory" and "validation") for out-of-sample testing in an effort to mitigate effects of data dredging if/when our quest for correlation runs amok.
Doing
- Arranging with BDE for Alex to receive CS 398 credit next term for BowTIE work.
- Performing Chi Square analysis of exploratory dataset to correlate abbreviated Parncutt fingerings with gender, reach, age, Hanon usage, technical practice, preparation actions, injury, etc.
- Looking at how well selecting fingering a in Exercise A predicts selecting fingering b in Exercise B. That is, do people have common patterns of fingering preference?
- Analyzing "consensus" of finger choice that follows abbreviated Parncutt fingering. How arbitrary were these sequences? Can we identify more suitable sequences in our data?
- Doing more basic descriptive statistical analysis of survey data.
- Evaluating Tableau for easier (and richer) data visualization. (SQLite support missing for OS X.
Struggling
- Can we legitimately treat fingerings as categories?
- How can we conflate the unpopular fingerings meaningfully?
- Not sure how out-of-sample testing will complicate contemplated ad hoc category definition.
