Natural Gas Reforming/Gasification: Synthesis gas, a mixture of hydrogen, carbon monoxide, and a small amount of carbon dioxide, is created by reacting natural gas with high-temperature steam. The carbon monoxide is reacted with water to produce additional hydrogen.
Measurement scales are used to categorize and/or quantify variables. This lesson describes the four scales of measurement that are commonly used in statistical analysis: nominal, ordinal, interval, and ratio scales. Each scale of measurement satisfies one or more of the following properties of measurement.
Ordinal Scale Measures in terms of such values as more or less, larger or. smaller, but without specifying the size of the intervals. Example: rating scales, ranking scales, Likert-type scales. Interval Scale Measures in terms of equal intervals or degrees of. difference but without a true zero point.
