Past data in statistics on the variable of interest is used to assess the p.m.f., only if we have reasons to believe and verify that conditions similar to the past would prevail. The frequency of occurrence of each and every of the values of the variable and its relation are noted down and the relative frequency of each of the values is taken noted as a probability measure.
The basis lies in the Relative Frequency Approach which likes to equal the resulting p.m.f. with the corresponding frequency distribution. Thus, under the assumption that buyer behaviour and condition has not changed much, we would take the past sales data of a product to find also the probability distribution of future sales. While frequency distribution is generally a representation of what has happened in the past, p.m.f. represents what we would expect also in the future.
Statistics Assignment Help could easily explain that you can see that the probability distribution of the random variable daily sales of American Express" has been estimated and calculated from past data. If we denote the random variable by x, we can write down the p.m.f. with help of other variable.
This method is applied if there is no viability of past data, and the situational condition of interest does not resemble any known processes in Probability theory. Statistics assignment help give us example suppose a record manufacturing company is contemplating the introduction of a new singer. ‘Before introducing new singer, they want to find out the likely future sales of an L.P. record of the new person in the first year of the release of the record. The random variable would be the sales in first year.
Statistics assignment help provide one step ahead in solving assignment of complex nature by increasing knowledge of subject. Importance of Statistics homework help increasing because of application of statistics in all most all science subject as well as.
