How to calculate the absolute deviation ?

You will need:
  • Baseline
  • resulting figure.
# 1

In order to calculate the absolute deviation from the need to take the resulting figure base.The deviation is expressed in absolute value, that is, without taking into account plus or minus sign before the value.Upon receipt of the rejection is possible to estimate the trend in value.In some measure the absolute deviation is used to determine how the value obtained as a result of experience, different from the norm.

How to calculate the percentage deviation?To calculate the absolute deviation as a percentage necessary to calculate the percentage of the resulting deviation from the benchmark.Therefore you need to calculate the absolute deviation multiplied by one hundred percent, and divided by the benchmark.The calculated value is calculated as a percentage and shows what proportion of the benchmark takes absolute deviation.

# 3

How to calculate the average deviation?To calculate the average deviation of the series of numbers, you

must first calculate their arithmetical mean value.Then calculated the absolute deviation of each number from a number of the resulting average value.Then you need to find the arithmetic average of the absolute deviations of the absolute deviations.The result will be the mean absolute deviation of a set of numbers or a standard deviation.

How to calculate the standard deviation?The standard deviation is calculated by calculating the absolute deviation from the mean value of the set.This indicator provides a measure of how far the values ​​of the plurality of spaced apart on average.The lower the standard deviation, the closer to the average value is set.If the value of the standard deviation is large enough, then the set of values ​​different from the average on a sufficiently long period.

How to calculate the relative deviation?Relative deviation is the ratio of the absolute deviation to the base value, expressed as a percentage.That is, to calculate this value, the value of the absolute value is divided by the value of the base value and the result multiplied by one hundred percent.The resulting value represents the percentage of deviation from the base value.
