Levels of MeasurementDifferent types of data: Nominal Data - Labels and names. Categorical / group data. Ordinal Data - Data that makes sense to put in rank order (e.g. Winners in a race) Interval Data - Accurate data measured in fixed intervals (e.g. seconds, cm) Ratio Data - Similar to interval data - "Data that has and begins with a real zero"
