2. For example, the average score of teachers =( 10+9)/2=9.5, and the average score of students =( 10+8)/2=9. According to the weights of 4, 3, 2, 1, we can calculate a classmate's evaluation score as follows:
9× 0.4+9.5× 0.3+9× 0.2+9× 0.1= 9.15.
Extended data:
Generally speaking, there are several ways to set weights:
1, subjective experience method
Evaluators directly set weights for indicators according to their past experience, which is generally applicable to situations where evaluators are very familiar with and understand the evaluation objects.
2. Queue classification of primary and secondary indicators
This is a common method, also known as A, B and C classification. As the name implies, its specific operation is divided into two steps: queuing and setting weights: queuing is to arrange all indicators in the evaluation index system according to certain standards, such as their importance; Setting the weight is to set the weight according to the indicators of A, B and C on the basis of queuing.
3. Expert investigation method
This method is to hire relevant experts to conduct in-depth research on the evaluation index system. Each expert independently sets the weight of the evaluation index, and then averages the weight of each evaluation index as the final weight.
For the same indicator, different departments and personnel, the weight of each indicator should be different; Data from different sources have different weights.
In the practice of evaluation, we should use a variety of methods to scientifically set the index weight. The usual practice is to set indicators mainly according to their importance and adjust them as needed.
