<h2>Repository for "Developmental trajectories in the understanding of everyday uncertainty terms"</h2> <p>This repository contains the data, code, and analyses for the paper "Developmental trajectories in the understanding of everyday uncertainty terms" (Meder, Mayrhofer, & Ruggeri, 2020).</p> <h3>A: Data</h3> <ul> <li>The behavioral data of all participants is located in <code>data/everyday_uncertainty_terms.csv</code></li> <li>The data for the re-analysis of Biehl & Halpern-Felsher (2001) is located in <code>data/Biel_Halpern-Felsher_2001_means_sd_Table1.csv</code>. The file contains the means and standard deviations reported in their Table 1.</li> </ul> <h3>B: Analyses, code, and plots</h3> <ul> <li> <p>Code for reproducing all analyses and plots of the behavioral data are in <code>everyday_uncertainty_terms.Rmd</code>, which a provide step-by-step guide of all analyses and plots. The R Markdown file loads the data and conducts the analyses, rendering results in <code>everyday_uncertainty_terms.html</code>.</p> </li> <li> <p>There are also separate R files with code for running all analyses and generating plots, which can be found in directory<code>/plots</code>:</p> <ul> <li><code>data_preprocessing.R</code>is a helper function that reads and re-formats the raw data; returns a data frame with all relevant data for the analyses</li> <li><code>behavioral_analysis.R</code> contains code for analyzing the behavioral data</li> <li><code>density_plots.R</code> generates densities of fitted Beta distributions and plots them. </li> <li><code>analysis Biehl et al 2001.R</code> conducts an analysis of the data reported in Biehl, M., & Halpern-Felsher, B.
