Extended data
Weighted average is to multiply each value by the corresponding weight, and then add up to get the total value, and then divide it by the total number of units.
The weighted average depends not only on the value of each unit (variable value) in the population, but also on the number of occurrences of each value. Because the number of occurrences of each value plays a role in weighing its influence in the average, it is called weight.
meaning
Weight is a relative concept, aiming at an indicator. The weight of indicators refers to their relative importance in the overall evaluation. Weight refers to the quantitative distribution of the importance of different aspects of the evaluated object in the evaluation process, and the role of each evaluation factor in the overall evaluation is treated differently. In fact, an evaluation without focus is not an objective evaluation.
App application
1, the application in futures
On the one hand, if the futures price is higher than the weighted average price, the latter is moving up slowly or quickly, which means that the market situation will easily rise, but it is difficult to fall or continue to improve. On the other hand, if the futures price is higher than the weighted average price, the latter will run in a narrow range or downward, which indicates that the market will slow down or turn around.
Therefore. At the same time, we should also pay attention to the change of the gap between the futures price and the weighted average, and observe the opportunities for entering and leaving when the gap is too narrow or too wide. If the market is still rising or falling, the narrow gap can provide a good opportunity to make the market better or worse. On the other hand, even if the market situation is still rising or falling, the phenomenon of excessive gap can provide a good opportunity to take notes against the market trend.
2. Application in municipal budget
In the calculation of municipal engineering quantities, we often encounter numbers with the same subtitle type but different quantities. If you calculate the engineering quantity and list the quota subtitle. This is not only time-consuming but also error-prone. If you bid, time is not allowed. Project bidding is related to the life and death of construction enterprises.
Therefore, how to calculate the engineering quantity quickly, efficiently and accurately in a short bidding time, how to change the thinking of engineering quantity calculation in the past years, and how to explore a set of engineering quantity calculation methods that meet the bidding requirements are important topics for every municipal engineering cost personnel. In order to improve work efficiency, save bidding time and improve the winning rate, the concept of weighted average method is adopted to design its application in municipal budget.
