One method is to replace all uncertain parameters with expected values and then perform a sensitivity analysis. If a decision-maker indicates how sensitive the choices will be to changes in one or more inputs, it will be a relief. The use of models by managers and decision-makers is one of the most important uses of sensitivity analysis. Only by doing sensitivity analysis repeatedly can all of the content required for the decision model be fully utilized. In addition, it aids decision analysts in comprehending the uncertainties, advantages, and disadvantages, as well as the limitations and breadth of a decision model.

Median or mean is used in calculating the mean deviation. But only mean is used to calculate the standard deviation. In it all the items of a series are not given equal importance. It can be calculated merits and demerits of mathematical economics in the absence of any one of the items. It can’t be calculated unless all of the observations are known. Of the ratios of the corresponding observations in a series is equal to the ratios of their G.M.

The trend values for other years can be computed by successive addition or subtraction for each year ahead or behind any year. H.M is based on all the aspects of a series, i.e. it cannot be calculated by neglecting any item of a series. The harmonic mean is employed in finance to determine the average multiples like the price-income ratio, etc. In general, the harmonic mean is used when there is a requirement to give higher weight to the smaller items.

Commerce is the exchange of goods and services between individuals, businesses, and countries. It involves the buying and selling of goods and services, and it is a vital part of the global economy. Commerce can take place at local, national, or international levels, and it has been facilitated by advances in technology and transportation.

It cannot be determined even if one of the values is not known because it takes into consideration every item in the series in computation. Has also a plus point being a calculated quantity and is not based on position of terms in a series. Fluctuations are minimum for this measure of central tendency when repeated samples are taken from one and the same population. As the mathematical formula is rigid one, therefore the result remains the same. Commerce stream has well defined curricula given by the esteemed academicians where your interest and career have been taken into the consideration.

### Is mathematical economics good?

Textual data is used in an increasing number of business and research situations, and Information Systems researchers come across it in a variety of settings. Books, journals, articles, newspapers, jurisprudence databases, corporate information, and the Web are all examples of text documents. A text database is a system that keeps track of a large text collection and makes it accessible in a timely and accurate manner.

With the help of data given calculate Standard Deviation. The product of all observations will remain the same if each observation is replaced by the G.M. If any of the values of a given series is 0 then its harmonic mean cannot be determined as the reciprocal of 0 doesn’t exist. The harmonic mean can also be evaluated for the series having any negative values.
