One part of our work in QHELP is the creation of educational R Shiny Apps. These apps let the learners experiment how changes in parameters of quantitative procedures influence the results. Below you find the apps written by the consortium partners.
Validating BLIM-simulated Data
This app does a series of BLIM simulations and shows the dependence of the Distance Agreement Coefficient from the noise. The app was inspired by a student app from the 2019 seminar.
LexOPS
LexOPS finds characteristics of words from large corpora to be used in lexical studies.
Learnr Tutorial on Linear Regression
Conditional Testing
There is a PDF Document available for download which contains information about the app that is also available through the app’s help buttons.
Properties of Relations
This app allows you to define an arbitrary binary relation on a set of five items and shows you whether certain properties are fulfilled.
Modelling PISA Data by Clusters
An illustration of statistical learning and visualisation techniques using real-world data (PISA).
Distributions
This app illustrates the effect of violations of assumptions for the F distribution. It is an update of a TquanT app.
QQplot
This Shiny app is meant to let you play around with a few different distributions (Normal, Skew Normal, Cauchy, Skew Cauchy), and check what the effect of different variables (scale, location and shape) on their qq-plot is.
The qq-plots are all a comparison with a default normal distribution (mean=0, sd=1). There is a large slider you can use to track specific percentiles on all graphs. This Shiny app was made for teaching purposes.
Modeling the 2018 PISA Dataset based on PCA and Clustering
A series of interactive tutorials introducing principle component analysis, clustering, linear modelling and cross-validation for large datasets.
Animated learning Paths v4
This app illustrates the concept of learning paths in a knowledge structure. It is an extension of an app from the TquanT project.
Reliability
How would your house look like if the carpenter building the windows is not fully reliable?
n-Neighbourhood
Illustrating neighbourhoods in knowledge structures
LearnR Tutorial on Knowledge Space Theory
A learnr tutorial including several R Shiny Apps developed within the QHELP and TquanT. projects.
R & Shiny
A set of three documents: An R refresher and a Shiny introduction, together with exercises.
