How to find absolute increase

Absolute values in statistics are called aggregated indicators of dimensions of social phenomena in a given place and time. The absolute size of its value, taken by itself without regard to the size of other phenomena. The absolute values are named numbers, which Express sizes of the phenomena in specific units (people, RUB, pieces, man-days, etc.). Absolute growth refers to the performance series. The time series (time series) is a series of statistical quantities characterizing the change of phenomena in time.

Instruction

1. Determine the rate of absolute increase on a basic basis as the difference between the current and the initial level of the series by the formula:
   Δi = yi – yo,
   
   where yi is the current value of number,
   
   yo is the initial level of the series.
   Example:
   
   In 1997, produced goods to 10 million tons in 1998 to 12 million tons, in 1999 - 16 million tons, in 2000 - 14 million tons.
   
   Δi = 12 - 10 = 2 million tons
   
   Δi = 16 - 10 = 6 million tonnes.
   
   Δi = 14 - 10 = 4 million tons.
2. Calculate the rate of absolute increase on a chain basis as the difference between the current and previous level number according to the formula:
   Δi = yi – yi-1,
   
   where yi is the current value of number,
   
   yi-1 - previous level.
   Example:
   
   In 1997, produced goods to 10 million tons in 1998 to 12 million tons, in 1999 - 16 million tons, in 2000 - 14 million tons.
   
   Δi = 12 - 10 = 2 million tons
   
   Δi = 16 - 12 = 4 million tons.
   
   Δi = 14 - 16 = -2 million tons.
3. Calculate the average of the absolute gain according to the formula:
   
   _
   
   Δ = yn – y1/n-1,
   
   where y1 is the first level of the series,
   
   n is the number of levels of a number,
   
   yn - the final level of the series.
   Example:
   
   In 1997, produced goods to 10 million tons in 1998 to 12 million tons, in 1999 - 16 million tons, in 2000 - 14 million tons.
   
   _
   
   Δ = 14-10/4-1 = 1,3 million tons
