7 Summary of Session 5

In this session you learned how Euler diagrams are used as a tool for reasoning, and you saw them applied to logic problems and to representing sets of things. You also learned:

  • about the two important operations that can be applied to sets – union and intersection.
  • how to define sets in Python, and how to use Python to find the intersection and union of sets.
  • how Euler diagrams can be used to reason about the numbers of objects in sets, and how this can help assess the probability of something happening. This led on to the law of small numbers, whereby random fluctuations produce bigger variation among small populations than among large ones.
  • about the false positive paradox. You saw an example worked out first using Euler diagrams, and then by calculations in Python.

Session 6 returns to the theme of argument maps and explores some of the benefits of argument mapping. You will be introduced to FreeMind, a digital thinking tool which is useful for constructing argument maps. You will also learn a recipe for creating argument maps from arguments expressed in text.
