The average score = “the sum of the multiplication of the academic activities to their weights” divided by “the sum of the weights”.You can calculate the weighted grade by using the suggested formulas: If you set the weight for any type of work other than 1, the system will calculate a weighted average score with a new value being reflected in the final result. By default, all tasks have a standard weight of 1, and the system calculates the average score as the arithmetic mean. And it is this weight that is used in calculating average score. Each type of academic activity/ task/ assignment has its own fixed weight. Now we will show you how to calculate your average grade. How to Calculate a Weighted Average: The Easiest Way Not satisfied with the final result? Get expert help with essay writing or other academic assignments at Stud圜rumb. For example, the weight of the homework assignment is 2 course work has the value of 6 the weighting factor of quizzes is 8, while the same for an exam is 10. The value can be selected between 1 and 10 and is supposed to display how important a particular assignment is. Thus, the figure is a more objective indicator of the academic performance of a student. On the other hand, the weighted average score is calculated taking into account their weight, that is, the importance coefficient of each assignment. You can simply calculate your average test scores and figure out what your final grade will be. Looking how to calculate your GPA, simply remember it's the sum of all scores divided by their number. Although the two may seem to be the same, they have their own distinctive features. So, check out the course summary at the end, and best of all, explore Excel 2013 on your own.What Is the Difference between the Weighted Average and the GPAīefore we explain how to calculate weighted grades, let’s figure out the main difference between the GPA and the weighted average point. Now, you have a good idea about how to average numbers in Excel. If we had just averaged the Test scores, the value would be 75.5, a significant difference.įor more information about the SUMPRODUCT and SUM functions, see the course summary. To get the Weighted Average, you divide by the Total of the weights. SUMPRODUCT is essentially the Sum of Test 1 times its weight, plus the Mid-term times its weight, and so on. We then divide the outcome of SUMPRODUCT by the SUM of the weights.Īnd this returns the Weighted Average of 80. The SUMPRODUCT function multiplies each Test’s score by its weight, and then, adds these resulting numbers. We’ll use the SUMPRODUCT and SUM functions to determine the Weighted Average. In this example, the Mid-term and Final exams have a greater weight than Tests 1 and 2. With a Weighted Average, one or more numbers is given a greater significance, or weight. The numbers are added together and then divided by the number of numbers, as in this example, which returns an unweighted average of 5. Usually when you calculate an average, all of the numbers are given equal significance. The formula works by dividing the total cost of the two orders by the total number of cases ordered.Ĭalculate the average of a group of numbers To get the correct average, use this formula to get the result (28 cents per shipment): The math doesn’t take into account that there are more cases being sold at 30 cents than at 20 cents. If you averaged the cost of each shipment this way (0.20+0.30)/2 = 0.25, the result isn’t accurate. But a second shipment of 40 cases costs 30 cents per case, because pencils are in high demand. Use the SUMPRODUCT and the SUM functions to find a Weighted Average, which depends on the weight applied to the values.įor example, a shipment of 10 cases of pencils is 20 cents per case. Usually when you calculate an average, all of the numbers are given equal significance the numbers are added together, and then, divided by the number of numbers.
