Questions and answers
How do I calculate a weighted average?
Multiply each value by its weight, add the results and divide by the sum of the weights. Grades 8 (weight 2) and 6 (weight 1) average (16 + 6) ÷ 3 = 7.33.
What is the difference between mean and median?
The mean adds all the values and divides by how many there are; the median is the middle value once they are sorted. One very high or very low value does not pull the median.
