The mean absolute deviation is the average of the positive distances of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out). The MAD helps determine whether the set's mean is a useful indicator of the values within the set.
95 - 98+. Although Potassium only has two stable isotopes (K-39 and K-41), the long-lived radioisotope K-40 is often also regarded as a stable isotope. Potassium Isotopes, mainly K-40 and K-41, are used to study the impact of potassium on the growth of plants and of the human cardiovascular system.
Overview. Potassium nitrate, also known as saltpeter, is an odorless powder composed of transparent and/or white crystals. It is prepared commercially for use in a number of products, including gunpowder, fireworks, matches, rocket propellants, ceramics, glass and fertilizers.ire. While potassium nitrate itself is not combustible, it is considered to be a strong oxidizer, meaning that it releases oxygen when it breaks down, or decomposes. This oxygen release greatly enhances the flammability of other materials.
