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.

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.

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

_

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

Note

The calculation of the average of the absolute growth it is necessary to summarize the results of the development of phenomena over a single interval or time of the available time series.

Useful advice

Performance indicators are calculated on base and chain-based. Basic indicators of the dynamics is obtained by comparison of the levels of the series with the same original level. Chain performance indicators are obtained by comparing each row with the previous one.
