Kestrel causes of death

Use this diagram to explain how proportions and percentages can be easier to interpret than raw counts.

Proportions and percentages have similar information but the lack of leading zeros in the column of percentages makes it easier to quickly assess differences.

The data set shows the causes of death of kestrels (a bird of prey) in Britain between 1963 and 1997. (Carcasses were sent to the researchers in response to advertisements in bird-watching magazines and journals and the cause of death was found from information sent by the finder and examination of the carcass.)
