Weight ratio calculation paper calculation: weight can be judged and calculated by dividing multi-level indicators, and the commonly used methods are AHP, fuzzy method, fuzzy AHP and expert evaluation method.

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 and 1, we can calculate a student's evaluation score as 9× 0.4+9.5× 0.3+9× 0.2+9× 0.1= 9.15.

weighted average

That is, each value is multiplied by the corresponding weight, then added to get the total value, and then divided by the total number of units. The weighted average depends not only on the value (variable value) of each cell in the population, but also on the number of times (frequency) that each value appears. Because the number of occurrences of each value plays a role in weighing its influence in the average, it is called weight.
