# Prior Setting In Practice: Strategies and rationales used inchoosing prior distributions for Bayesian analysis This repository contains supplementary materials for the CHI 2020 submission, *Prior Setting In Practice: Strategies and rationales used inchoosing prior distributions for Bayesian analysis* The repository (OSF Storage) is structured as follows: - This study is preregistered on AsPredicted.org. The preregistration document can be found in the root directory or [online on AsPredicted](https://aspredicted.org/qw2py.pdf). - The directory labelled *Survey* contains materials used in the survey. The survey had three separate conditions, the materials for them can be found in separate directories within the *Survey* directory: - *Condition 1 - Parameter scale density vis* directory contains the first two pages for the `Parameter scale density visualization` condition. They survey can be viewed online [here](https://abhsarma.github.io/interactive-prior-setting/Survey/Condition_1_Parameter_scale_density_vis/0c-user-study-1.html) (links to a github hosted website). - *Condition 2 - Response scale density vis* contain the first two pages for the `Response scale density visualization` condition. They survey can be viewed online [here](https://abhsarma.github.io/interactive-prior-setting/Survey/Condition_2_Response_scale_density_vis/1t-user-study-1.html) (links to a github hosted website). - *Condition 3 - Prior predictive density vis* contain the first two pages for the `Prior predictive density visualization` condition. They survey can be viewed online [here](https://abhsarma.github.io/interactive-prior-setting/Survey/Condition_3_Prior_predictive_density_vis/2t-user-study-1.html) (links to a github hosted website). - The *page 3 of the survey*, which asks participants some open-ended questions can also be found within the *Survey* directory. - The directory labelled data analysis contains the two R scripts detailing our analysis of the data, and our calculation of predictive probability mass (depcited in Figures 4 and 5). It also contains the deidentified responses to our survey. - The directory labeled *user-study-html* contains the materials used during the follow-up interviews. Although this was different for each interviewee, an example can be found [here](https://abhsarma.github.io/interactive-prior-setting/user-study-html/1t-user-study.html) (links to a github hosted website). This document is for a participant who was in *Condition 2 - Response scale density vis* in the survey. - The directory labelled *Transcripts* contain the transcripts from the follow-up interviews. - The semi-structured interview protocol we used for our follow up interviews can be found in the root directory.
