Parameters and statisticsA parameter describes the whole population and a statistic describes the sample in hand.Lesson
Populations, samples and censusThe whole group you care about, and the part you actually measure.Lesson
Random samplingEvery member equally likely, so the sample looks like the population.Lesson
Sampling variability and simulating itDifferent samples from the same population give different statistics, and that spread is predictable.Lesson
Simple random samples and the sampling frameA sample drawn so that every group of the chosen size is equally likely.Lesson
Stratified random sampleSplitting the population into similar groups first, then sampling at random inside each.Lesson
Systematic samplePicking a random start and then taking every so many individuals down a list.Lesson
