* This app allows you to upload a dataset (".csv") and to visualize the distributions of the different variables.
* **Using the app** + The aim of this app is to teach students a more intuitive understanding of distributions. Thereby, they can guess distributions and discuss them subsequently. + Choose different variables in the dataset. + Choose whether to display absolute or relative frequencies. + Choose whether to see 2d or 3d distributions. + Use your own data. It should have the format of the default file.
* The **preloaded default dataset** is a subset of the Swiss European Social Survey (ESS6e02). It contains the following variables... 1. Trust in police = {0-10} = {not trust at all, ... , complete trust} 1. Trust in politicians = {0-10} = {not trust at all, ... , complete trust} 1. Political interest = {0-3} = {not at all interested, ..., very interested} 1. Voted last election = {0, 1} = {no, yes} 1. Party voted last election = {8 different parties} 1. Citizenship = {0, 1} = {no, yes} 1. Happyness = {0-10} = {extremely unhappy, ..., extremely happy} 1. Health = {0-4} = {very bad, ..., very good} 1. Age = {16-96} 1. Household income (10 categories) = {0-9}
* **Issues** + Naturally, the visualizations make sense for variables with few categories, e.g. 3d plot becomes very small when plotting age.
