What you'll be able to do
- Summarising a distributionChoose a summary statistic that fits the distribution's shape and say why the other would mislead
- Variation and spreadReport a spread alongside a central figure, in units the reader can act on
- Reading a chart honestlyName what a chart's construction is doing to the reader's impression, and redraw it fairly
- Population and sampleState precisely which population a figure supports a claim about, and which it does not
- Sampling biasIdentify who is missing from a dataset and say which direction their absence pushes the result
- Sample size intuitionSay whether a reported difference is large enough to distinguish from noise at the sample size given
- Uncertainty and intervalsReport a figure as a range and state correctly what the range means
- What significance does not meanCorrect a claim that treats a significant result as a large or important one
- Looking until you find somethingRecognise a finding produced by repeated slicing and say what would test it properly
