When teaching an introductory level class, the teachers I know tend to invent some numbers and a story in order to exemplify the method they are teaching.
What I would prefer is to tell a real story with real numbers. However, these stories needs to relate to a very tiny dataset, which enables manual calculations.
Any suggestions for such datasets will be very welcomed.
Some sample topics for the tiny datasets:
- correlation/regression (basic)
- ANOVA (1/2 ways)
- z/t tests - one/two un/paired samples
- comparisons of proportions - two/multi way tables
