Inference as a dynamic concept map

Many students find it hard to understand the fundamental concepts in inferential statistics. This becomes apparent when students are mixing up population parameters and their estimates. Reasons why inferential statistics is so hard to understand are given and concept maps are introduced as a way to facilitate understanding. Two computer programs are described: ‘Sila’, which supports teaching of inferential statistics by means of a dynamic concept map and ‘PQRS’, a probability calculator that can help studying distributions.
