What is a Weighted Average?

The weighted average is to multiply each value by the corresponding weight, then add up and sum to get the overall value, and then divide by the total number of units. The weighted average value depends not only on the value of each unit (variable value) in the population, but also on the number of occurrences (frequency) of each value, because the number of occurrences of each value weighs its impact on the average The importance is called weight.

Weight is a relative concept,

There are many forms of "weight" in the weighted average, and they are due to. The change of "power" will result in very different results. His particularity is getting more and more attention and its application is becoming more and more extensive.

Application of weighted average in futures

On the one hand, if the futures price is higher than the weighted average, the latter will move up slowly or move up rapidly, which means that the market conditions will rise or fall or continue to improve. in contrast. If the period price is lower than the weighted average, the latter moves slowly or rapidly downwards, which implies that the market conditions will fall easily or continue to decline.

On the other hand, if the futures price is higher than the weighted average effect, the latter moves in a narrow range or is moving downward. Inspiration: market conditions will slow down or turn around and fall. Conversely, if the futures price is below the weighted average, the latter is moving in a narrow range or is moving upward, which implies that the market conditions will slow down or turn around and rise. The reason is that because the futures price cannot be supported by the same moving direction of the weighted average due to the uptrend or downtrend, the space for further ups and downs will become limited. It should be noted that the weighted average will have a pulling force on the futures price and prevent its increase or decline from expanding.

therefore. At the same time, we should also pay attention to the change in the gap between the futures price and the weighted average, and observe the market entry and exit opportunities when the gap is too narrow or too wide. If the market conditions are still rising or falling, the phenomenon of too narrow a gap can provide a good opportunity for the homeopath to make a good or a weak one. on the other hand. Even if the market conditions are still in the rising or falling waves, the phenomenon of too wide a gap can provide a good opportunity for the contrarian market to make small bets. In the end, we must remember that just because the cumulative increase or cumulative decline in futures prices is huge, without the simultaneous calculation of the weighted average's upward or downward shifts, we rush into the market against the trend to make it weaker or better.

Application of weighted average in municipal budget

In the calculation of municipal engineering quantities, we often encounter figures with the same subheading type but different numbers. If one by one calculate the amount of engineering. List the quota subheadings one by one. Not only is it laborious and time consuming, it is also prone to errors. If it is a bid, time is not allowed. Project bids have a bearing on the lives of construction companies. Therefore, how to calculate the project quantity at high speed, efficiency and accuracy within a short period of bidding time, how to change the thinking of the project quantity calculation over the past years, and explore a set of method for calculating the quantity that meets the bidding requirements, is placed in the cost of each municipal project Important issues before personnel. Therefore, the weighted average method plays an increasingly important role in the calculation of engineering quantities. In order to improve work efficiency, save bidding time, and increase the bid winning rate, the application of its municipal budget was designed using the concept of weighted average method ^[1] .

In short, in daily life, we often encounter the case of calculating such as the weighted mean. For example, when applying for employment, a college student will calculate his performance according to a certain weight based on his professional knowledge, work experience, and instrument image. This uses a weighted average. The weighted average reflects the influence of the importance of each data in a set of data on the overall concentration trend. In weighted averages. "Weight" has a clear meaning-it indicates how important a certain data is in a set of data, so we must study the weighted average effect in combination with specific cases. Understanding that the size of the weighted average is not only related to each data in a set of data, And it is also affected by the weight of each data. The larger the weight, the greater the impact on the average effect size. The smaller the contrary.

The generation of weighted average is a major breakthrough for human beings. It will play an important role in life practice and will have a great impact, which will make the uninterpretable fair events tend to be rationalized. In line with the scientific concept of development.
