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.
The interval scale of measurement is a type of measurement scale that is characterized by equal intervals between scale units.A perfect example of an interval scale is the Fahrenheit scale to measure temperature.The scale is made up of equal temperature units, so that the difference between 40 and 50 degrees Fahrenheit is equal to the difference between 50 and 60 degrees Fahrenheit.With an interval scale, you know not only whether different values are bigger or smaller, you also know how much bigger or smaller they are.he scale is made up of equal temperature units, so that the difference between 40 and 50 degrees Fahrenheit is equal to the difference between 50 and 60 degrees Fahrenheit.
