I made a poll among 8 persons on the audition quality. The individuals had to rank between 1 and 5 how they could hear according to:
* two different systems : siemens and phonak
* for 5 different styles: choral, classical, opera, lithurgie and pop
* and 3 different programs : (P1): default program (P2): special program to listen to music (P3): noisy environment
I need you to carry out the following signed ranked Wilcoxon tests for me and to write a report on the assumptions, results tables and graphs of the project:
Test 1: P2 is better than P1?
Please break down the test according to styles, systems and properties (sonie, etc...)
Test 2: P2 better than P3?
Please break down the test according to styles, systems
Test 3: P2 on phonak better than P2 on Siemens?
Please break down the test according to styles and properties
The datasets are uploaded, there is one dataset per individual and system, hence 2*8 csv files.
I need a graph that summarizes the statistics for my oral presentation
