Weighted Average Calculator

The weighted average, also known as the weighted mean, is easily computed by our weighted average calculator. This statistical measure takes into account the importance or weight of each number in a dataset. It is calculated by multiplying each number by its corresponding weight, summing these products, and then dividing by the total sum of weights. This method gives more significance to certain numbers based on their importance in the dataset.

Weighted averages are extensively used in various real world scenarios where certain data points carry more significance than others. Some common applications include:
• Grades and Courses: Calculating the weighted average grade in a course based on different assignments, exams, and their respective weights.
• Financial Investments: Determining the weighted average return on investment (ROI) considering the varying amounts invested and their durations.
• Product Reviews: Computing a weighted average rating for a product based on customer reviews and the weight assigned to each review.
• Exam Scores: Calculating the weighted average score of a student across multiple exams with different point values.

Here are the weighted average examples to calculate weighted average in different set of data.
