💡 Quick Review
Statistics and Probability
Use centre and spread together; consider sample size and whether data are representative.
Key ideas
- mean/median
- range
- outliers
- sample quality
- probability
Worked example: an outlier can affect the mean more than the median.
Common trap: A large sample can still be biased.
Key words
outlier — value far from the main pattern
sample — subset of a population
population — whole group of interest
distribution — pattern of data
relative frequency — proportion of trials with an outcome
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.
