Absolute values in statistics are generalized indicators that characterize the size of social phenomena in specific conditions of place and time. Absolute size is its value taken by itself without regard to the size of other phenomena. Absolute values are named numbers that express the size of phenomena in certain units of measurement (people, rubles, pieces, person-days, etc.). The absolute growth refers to the indicators of the series of dynamics. Series of dynamics (time series) are series of statistical quantities that characterize changes in phenomena over time.

Instructions
Step 1
Determine the absolute growth rate on a basic basis as the difference between the current and the initial level of the series using the formula:
Δi = yi - yo, where yi is the current level of the row, yo is the starting level of the row.
Example:
In 1997, products were produced for 10 million tons, in 1998 - 12 million tons, in 1999 - 16 million tons, in 2000 - 14 million tons.
Δi = 12 - 10 = 2 million tons
Δi = 16 - 10 = 6 million tons
Δi = 14 - 10 = 4 million tons
Step 2
Calculate the absolute growth rate on a chain basis as the difference between the current and the previous level of the series using the formula:
Δi = yi - yi-1, where yi is the current level of the row, yi-1 is the previous level of the row.
Example:
In 1997, products were produced for 10 million tons, in 1998 - 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
Step 3
Calculate the average absolute growth rate using the formula:
_
Δ = yn - y1 / n-1, where y1 is the first level of the row, n is the number of levels in the row, yn is the end level of the row.
Example:
In 1997, products were produced for 10 million tons, in 1998 - 12 million tons, in 1999 - 16 million tons, in 2000 - 14 million tons.
_
Δ = 14-10 / 4-1 = 1.3 million tons
