Data can be classified as being on one of four scales: nominal, ordinal, interval or ratio . Each level of measurement has some important properties that are useful to know. For example, only the ratio scale has meaningful zeros. A pie chart displays groups of nominal variables (i.e. categories).

What are the 4 basic units of the metric system?
The metric system is a system of measurement that uses the meter, liter, and gram as base units of length (distance), capacity (volume), and weight (mass) respectively.
What is unit and its types?
Answer: Unit-Unit is the standard assigned to measure physical quantity . ... The units of the fundamental quantities used in Physics are the fundamental units. Length, mass, time, tempera- ture, luminous intensity and the electric current are known as the fundamental quantities.
Which is the smallest unit of measure?
Answer: The smallest unit for length measurement in the metric system is the millimeter . The millimeter is highly used for small-scale measurements and tools that measure miniature object dimensions.
What level of measurement is grades?
An ordinal scale allows to order the objects. The ordinal scale is therefore sometimes also called rank scale. Examples: percentile ranks, grades at school, ranks in a race, Mohs’ scale of hardness (which exhibits unequal distances). Interval scale: equally spaced units along the scale without a predefined zero point.
What level of measurement is place of birth?
An interval-scale variable is measured on a scale of equally spaced units, but without a true zero point, such as date of birth. A ratio-scale variable is an interval variable with a true zero point, such as height in centimeters or duration of illness.
