The idea
Statistics turns data into insight, and its core habit is distributional thinking: data vary, and the whole distribution often reveals more than the center.
In practice
Two classes share a median of seventy, but one has scores bunched together and the other spread wide.
Where people slip
Number-crunching is a small part of statistics; planning a study and drawing honest conclusions matter as much.
