Now that our data is organized we can calculate the weighted average. Lab 1st Major Test 77 0.23 77(0.23) 2nd Major Test Final Exam Score 89 0.2 89(0.2) 69 67 Weight (Decimal) Product 0.23 0.34 69(0.23) 67(0.34) Take the sum of the products over all data values and divide by the sum of all the weights. This is the weighted average. XW 89(0.2) + 77(0.23) + 69 (0.23) + 67(0.34) 0.2 + 0.23 + 0.23 + 0.34
