M-Tool data analysis script
This folder consists of two R scripts that can help you process the M-Tool data. The first folder contains an R-script that provides M-Tool users with a starting point for their data analysis. The script uses the edge list produced by M-Tool and transforms these into total number of nodes, total number of edges and various centrality measures (including in- and out-degree, in- and out-strength, mean in- and out-degree weight, weighted and unweighted betweenness). The script also includes code to visualize the data. Users need to download both scripts, save their data file in the same folder, and enter the name of their data file in the script to obtain the centrality measures. The output consists of long data, with a row for each node for each participant. The output data can be integrated with survey data for further analysis. The second folder consists of an R script that allows you to visualise the aggregated mental models across all your participants. Using the images you used in your data collection, you can create a visual representation of the combined mental models of all participants. You can tailor the figure using the instructions in the R script. For more information on M-Tool, see www.m-tool.org. Contact person: Karlijn van den Broek - researcher - k.l.vandenbroek@uu.nl
