Picturing & Analysing Data

Turning a wall of numbers into a picture you can read — from which chart fits which data, through mean, median and mode, to reading a real experiment without overclaiming. Four short steps, each with its own toy to play with.

1 Where it comes fromA picture beats a column of numbers. Pick the chart that tells the truth and watch the wrong one fall apart. 2 How to do itSummarise the middle — mean, median and mode — plus the range for the spread. Drag the dots and watch them update live. 3 Where it gets trickyAn outlier drags the mean, a chopped axis exaggerates, and correlation isn't causation. 4 Out in the wildRead a real experiment, judge the trend, and draw a conclusion you can actually defend.
