Okta Okta In meteorology, an okta is a unit of measurement used to describe the amount of cloud cover at any given location such as a weather station. Sky conditions are estimated in terms of how many eighths of the sky are covered in cloud, ranging from 0 oktas (completely clear sky) through to 8 oktas (completely overcast). In addition, in the SYNOP code there is an extra cloud cover indicator '9' indicating that the sky is totally obscured (i.e. hidden from view), usually due to dense fog or heavy snow. When used in weather charts, okta measurements are shown by
Theory of conjoint measurement to some kind of unit difference. Each level of "P" is a difference between the levels of "A" and "X". However, it is not clear from the literature as to how a unit could be defined within an additive conjoint context. proposed a scaling method for conjoint structures but he also did not discuss the unit. The theory of conjoint measurement, however, is not restricted to the quantification of differences. If each level of "P" is a product of a level of "A" and a level of "X", then "P" is another different quantity whose measurement is expressed as a
