A school uses merit based pay for teachers. Each teacher would be given a score between 1 (Far Below Expectations) and 5 (Exceeds expectations) in the following categories. The weight of each category is included.

Content Knowledge (20%)
Lesson plans (15%)
Instruction delivery (20%)
Classroom management (15%)
Student Performance (20%)
Supplementary Responsibilities (10%)
A teacher received the following scores. What was his weighted average?

Content Knowledge = 4

Lesson plans = 3

Instruction delivery = 3

Classroom management = 5

Student Performance = 4

Supplementary Responsibilities = 2

The teacher's weighted mean is ______________.

Answer 1

4*0.20 = 0.8

3 *0.15 = 0.45

3*0.20 = 0.6

5 *0.15 = 0.75

4 *.20 = 0.8

2 *0.10 =0.2

0.8 + 0.45 + 0.6 +0.75 +0.8 +0.2 = 3.6

weighted mean = 3.6
