If you are collecting data on a person’s height, which type of data is this ?
Ratio
Height is measured in units such as centimetres, has equal intervals between values and a true (absolute) zero – zero height means no height. Ratios are meaningful: 180 cm is twice 90 cm. These are the properties of ratio data.
Nominal data only name categories (e.g. gender, jersey number), ordinal data only rank (e.g. 1st, 2nd, 3rd in a race), and interval data have equal units but an arbitrary zero (e.g. temperature in °C), so ratios are not meaningful.
Hence, the answer is Ratio.
