WebA nominal variable (also known as a categorical variable) has a number of categories to which an observation can be assigned. Thus colour is measured on the nominal scale (or categorical scale ). For example, fungal cultures could be classified as 'white', 'yellow' or 'green'. Or you may record the number of mice that are white, brown, or brown ... WebAbsolute humidity is the measure of the amount of water vapor in air. Relative humidity tells how much water vapor is in the air relative to the amount it has the potential to hold at a given temperature and pressure. The instrument used to measure water vapor content in the air is called a hygrometer. WebThe term absolute humidity (AH) expresses the quantity of moisture in the air and is quantified in g/m 3. The absolute humidity depends strongly on the actual temperature. At low temperatures, the AH is low, but at higher temperatures the air carries much more moisture. For example, at 0°C: 4.9 g/m 3, at 30°C: 30.1 g/m 3. how do i get on the cloud
