A weighted mean, also known as a weighted average, is a statistical measure that takes into account the importance or significance of different values when calculating the mean. In a weighted mean, each value is assigned a weight, which represents its relative importance. The weighted mean is calculated by multiplying each value by its weight, summing up these products, and then dividing by the sum of the weights.

Using the Calculator

Calculating a weighted mean is a simple process when using the Weighted Mean Calculator. Follow these steps to find the weighted mean of a dataset:

  1. Data Input: Enter your dataset, which consists of values, into the provided input field. You can separate the values by commas, spaces, or line breaks.
  2. Weights: Assign weights to each corresponding value in your dataset. Weights can be whole numbers or decimals, and they represent the importance of each value. Ensure that the weights are in the same order as the values.
  3. Calculate: Click the "Calculate" button to obtain the weighted mean based on your data and weights.

Interpreting the Result

The Weighted Mean Calculator will generate the weighted mean of your dataset, taking into account the assigned weights. This result is a single value that provides an overview of your data while considering the significance of each value. Weighted means are particularly useful when certain data points have a greater impact on the overall mean than others.


Weighted means are used in various fields and scenarios, including:

  • Education: Calculating students' overall grades by assigning different weights to assignments, exams, and projects.
  • Finance: Determining portfolio returns in investments, with each asset assigned its own weight.
  • Market Research: Analyzing survey responses or market data while giving priority to specific demographics or responses.
  • Business: Evaluating employee performance by considering various factors, such as sales figures, customer feedback, and project completion.
  • Science and Engineering: Combining experimental results, measurements, or variables with varying degrees of importance.

By using the Weighted Mean Calculator, you can easily and accurately compute weighted means, making informed decisions and assessments across different fields.
