Mean deviation is easy to calculate. This measure is simple to understand. This can be calculated from any average. Its value is based upon all the (observations) items of the data. It is less affected by extreme observations. It gives us an idea about how the items are situated in the..

Merits: 1. Mean deviation is easy to calculate. This measure is simple to understand. 2. This can be calculated from any average. 3. It is less affected by extreme observations. Demerits: 1. This is mathematically incomplete because it ignores negat..

It has enabled us to explain the laws of chemical combination. Dalton was the first person to recognize a workable distinction between the ultimate particle of an element (atom) and that of a compound (molecule)..

This process gives soda of much higher purity (99.5%). It is less expensive as the raw materials are cheap and CO 2 and NH 3 are recovered to be used again. Calcium chloride is the only waste is the solution and so no pollution problems. Formation of sodium bicarbonate as an intermedia..

The five-kingdom classification has certain merits and demerits. However, it is largely the most accepted system of modern classification mainly because of the phylogenetic placing of different groups of living organisms. This system of classification looks more scientific and natural bec..

This classification is based on the most fundamental property of the elements - the atomic number, so it is more accurate. With the atomic number as the basis of this classification, the position of isotopes in one place is justified. The systematic grouping of elements into the four blocks..

The scores on a certain standardized test are known to have a mean of 100 and standard deviation 25. A person will get a merit certificate if he scores above 125. What is the probability that a person taking this test receives a merit certificate? => 0.1587 or 0.6587 or 0.3413 o..

The natural system of classification has been subjected to periodic reviewing as a result of the continuous input of information and new scientific tools being available on various aspects of living organisms. Various schemes of classification are now available, each having certain merit..
