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 JAR scales are usually category type scales with 5 points with the anchors as below: 1  Too sweet. 2  Slightly too sweet. 3  Just about right. 4  Slightly not sweet enough. 5  Not sweet enough.
