💡 Quick Review
Statistics
Choose summaries suited to the distribution and distinguish association from causation.
Key ideas
- mean/median
- IQR/range
- box plots
- scatter plots
- correlation
Worked example: strong correlation does not by itself prove causation.
Common trap: A line of best fit is a model, not a guarantee for every data point.
Key words
interquartile range — Q3−Q1
distribution — pattern of values
correlation — strength/direction of association
outlier — unusual value
bivariate — paired measurements on two variables
How to use this drill: review the short notes when learning, then close them on later attempts and practise from memory. The rotating bank delays a full set repeat for 30 attempts on the same browser.
