Arithmetic average index number
AVERAGE (number 1, number 2): returns the average (arithmetic mean) of its The cell indices have to be substituted by node indices (i,j) in the case of the These price relatives are then averaged to get the index number. The average used could be arithmetic mean, geometric mean or even median. Weighted index In short, the simple arithmetic average, both of prices and of quantities, may be used. Or, if it is worth while to put any finer point on it, we may take the weighted using definitions in equation (16.7). Thus, the Laspeyres price index PL can be written as a base–period revenue share weighted arithmetic average of the n The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three Simple geometric mean of price relatives. Aggregate with fixed weights. Marshal- Edge worth Price index number. Quantitative Aptitude & Business
Lastly, index numbers show changes in average. In effect, it means if the average change is 5% then some goods might not change exactly at 5%. Browse more

A CPI of x means it takes x times as much money now to buy a basket of goods as it did
Compute a price index with the (1) simple aggregative method and (2) average of price relative method by using both the arithmetic mean and geometric mean,
Price index number indicates the average of changes in the prices of representative But, in practice, arithmetic mean is used because it is easier to follow. 5. 28 Jun 2019 An arithmetic average is the sum of a series of numbers divided by the count of that series of numbers.

If you were asked to find the class (arithmetic) average of test scores, you would simply add An index number is a summary measure. Thus, its usefulness decreases as it tries to describe a complex situation which is too wide in scope. The arithmetic mean or any other form of averages becomes less and less representative. Such averaging is beset within certain technical difficulties.
