How to calculate the relative deviation

Relative figures represent the ratio of the absolute value of one to the other. They reflect the quantitative relationships between the studied phenomena. In calculating the relative deviation is compared one or more indicators to the base or base.

How to calculate the relative deviation

You will need:

- calculator.

Instruction how to calculate the relative deviation

Step 1:

A specific feature of the indicator deviation is that it allows you to escape from certain differences in the absolute values. This makes it possible to compare these effects, the absolute values ​​are not comparable.

Step 2:

Relative deviation is a deviation, calculated in relation to other values. Expressed as a percentage or a fraction. More often than not calculated in relation to any common parameter or option. The use of this index in the research increases the information content of the analysis and can more accurately assess changes.

Step 3:

Total calculation formula can be represented as follows: = Δo Hotch / cotton. Its components vary depending on which effect is taken as a basis of comparison.

Step 4:

If you want to relate one and the same figure in different time periods, we expect its rate of growth. He shows how to change the value in the accounting (current) period as compared to its baseline level: Tr = x1 / x0. If this figure is expressed as a percentage, it is a question of growth rate: Tpr = (x1 / x0) * 100%.

Step 5:

The relative magnitude of the planned target is the ratio of the planned and adopted as a basis for comparing the levels of the same phenomenon. The base serves as the value actually reached trait of the phenomenon investigated in the previous period. The calculation formula is: = OVpz HPL / cotton.

Step 6:

If we consider the implementation of a given level, we are talking about the "execution plan" concept. In this case, calculated with respect to the deviation is actually the result of the planned level: DPIG = Kph / HPL. It shows how many times the value obtained researched phenomenon is different from the planned level events for the same period.
