Question

Density of population in an urban area comes under the category of which data? Nominal data Ordinal data Ratio data Interval data

Answer 1

Answer is Ratio data

These are the different data scales of measurement.

• Nominal - denotes something like a label or name. Mostly answer for What? , Where? . Helps to classify data Eg. What are three main religion groups of India? Hindu, Christian, Muslim.
• Ordinal - mostly answers for how?, but do not show exact quantity. Eg. How is your day? Answer may be Happy, Very Happy. Also, ranking of the students in education.
• Ratio - Exact value of the data is represented and can measure a zero value Eg. Amount of expenditure for the month of august.
• Interval - Measurement is in terms of interval between two units. Cannot have a zero value. Eg. temperature is between 45 to 50 degrees.
