What are the advantages and disadvantages of harmonic mean?
It is capable of further algebraic treatment. It gives better result when the ends to be achieved are the same for the different means adopted. It gives the greatest weight to the smallest item of a series. It can be calculated even when a series contains any negative value.
What is a disadvantage of using the mean?
DISADVANTAGES. The important disadvantage of mean is that it is sensitive to extreme values/outliers, especially when the sample size is small.[7] Therefore, it is not an appropriate measure of central tendency for skewed distribution.[8] Mean cannot be calculated for nominal or nonnominal ordinal data.
What is the use of geometric mean?
The geometric mean is used in finance to calculate average growth rates and is referred to as the compounded annual growth rate. Consider a stock that grows by 10% in year one, declines by 20% in year two, and then grows by 30% in year three.
What are the advantages and disadvantages of mean mode median?
Advantages and disadvantages of averages
| Average | Advantage |
|---|---|
| Median | The median is not affected by very large or very small values. |
| Mode | The mode is the only average that can be used if the data set is not in numbers, for instance the colours of cars in a car park. |
What is the main advantage of the mean?
Arithmetic mean is simple to understand and easy to calculate. It is rigidly defined. It is suitable for further algebraic treatment. It is least affected fluctuation of sampling.
Why is geometric mean better?
The geometric mean differs from the arithmetic average, or arithmetic mean, in how it is calculated because it takes into account the compounding that occurs from period to period. Because of this, investors usually consider the geometric mean a more accurate measure of returns than the arithmetic mean.
What are the pros and cons of the geometric mean?
Pros and Cons of the Geometric Mean Pros: It is rigidly defined and its value is a precise figure. It is based on all observations. It is capable of further algebraic treatment. It is not significantly affected by fluctuation of sampling. It is not affected by extreme values.
Is geometric mean suitable for non-mathematics?
It is suitable for further mathematical treatment. It is not affected much by fluctuations of samplings. It gives comparatively more weight to small items. Because of its abstract mathematical character, geometric mean is not easy to understand and to calculate for non-mathematics person.
What are the advantages of the standard measurement method?
It is rigidly defined. It is based upon all the observations. It is suitable for further mathematical treatment. It is not affected much by fluctuations of samplings. It gives comparatively more weight to small items.
What are the advantages and disadvantages of Statistics?
When it comes to statistics we can say that there are 3 great advantages over it: Statistics allow a systematic working method to be carried out. Unfounded ideas are not the basis for this branch and avoid by all means making claims without any basis.
