Simple and weighted index number

Simple is you add up all the values, then divide by the total number of values. Weighted is when values take different importance, so you multiply by their weight (importance) then sum it all up, then divide by the total weight. Example: * 7 with Weighted Mean. Also called Weighted Average. A mean where some values contribute more than others. Mean. When we do a simple mean (or average), we give equal weight to each number.. Here is the mean of 1, 2, 3 and 4: In the case of a value-weighted index, the amount of outstanding shares comes into play. To determine the weight of each stock in a value-weighted index, the basic formula (without getting too complex for demonstrative purposes) is to multiply the price of the stock by the number of outstanding shares.

Construction of Weighted Index Number. 1] Weighted Average or Price Relatives Method. Here we calculate the ratio between the summation of the product of 

Unlike simple index numbers, weighted index numbers, as the name suggests, weigh items according to their importance with respect to the concerned variable. For example, when calculating the price index number if the price of a unit of rice is twice the price of a unit sugar then the rice will be weighed in as ‘2’ whereas sugar will be There are different ways of construction of index numbers.In general, construction of index number is further available for the division in two parts: Simple and Weighted. Furthermore, the simple method is classified into simple aggregative and simple relative. In the case of a value-weighted index, the amount of outstanding shares comes into play. To determine the weight of each stock in a value-weighted index, the basic formula (without getting too complex for demonstrative purposes) is to multiply the price of the stock by the number of outstanding shares. Compute the weighted aggregative price index numbers for $$1981$$ with $$1980$$ as the base year using (1) Laspeyre’s Index Number (2) Paashe’s Index Number (3) Fisher’s Ideal Index Number (4) Marshal-Edgeworth Index Number. There are two methods of computing the index numbers: (a) Simple index number and (b) Weighted index number. Simple index number again can be constructed either by – (i) Simple aggregate method, or by (ii) simple average of price relative’s method. Similarly, weighted index number can be constructed either by (i) weighted aggregative method The index number that is computed after assigning due weightage to different items under study is called weighted index number. In such a case, weights are assigned in an explicit manner either on the basis of the quantities, or on the basis of the values of the items consumed, or on any other rational basis. Simple Index Number. Simple index number is the ratio of two prices of a single commodity at two different time periods, expressed as a percentage. For example, a price index for per unit price of a commodity in January 2000 compared with January 2002 would be a simple price index. In order to see the calculation of simple price index or price
