The same approach can be used when choosing a university, a workplace, a house/apartment, and so on.Sathya Kattragadda, aka Mr. Note how #3 and #4 have fairly different scores across the different characteristics yet the same weighted mean score. Scoring several different laptops by using weighted scores calculated using their weighted average allows for easy comparison across all five categories by assigning just a single score for each laptop. Assuming there are five possible choices with roughly equal price and scores on each characteristic on a scale from 1 to 10, the weighted average score for each is calculated in the table below: Example weighted score comparison Laptop ID / Score The above weights represent that the most value is placed on the quality of the display, less on the video card and the battery longevity, and even less on weight and CPU power. Presented as a table: Example weights Characteristic The score will average five components: display quality, battery longevity, weight, CPU performance, and video card performance, each with a different weight. In this example we will explore the problem of calculating the mean score for laptop offers from different manufacturers. Compare this to the ordinary mean of 28 / 4 = 3.075.
In this case the weights are the number of credits for each course. Assume you have these four classes with the given grades and the number of credits for each class: Example weighted grade calculation (by number of credits) Class Calculating a weighted gradeĪ common example of using weighted averages is to compute a weighted average grade (weighted GPA) from a number of classes or courses taken in high school or university. The formula describes a process in which the values are iteratively multiplied by their weight, added up, and then divided by the sum of weights. This weighted mean equation can be expanded for easier comprehension like so: Where x i are values of the variable X, w i are the associated weights, and Σ, the Greek upper-case letter "sigma", is the symbol for the sum operation. The formula for computing a weighted arithmetic mean is as follows: Note that weight values cannot be negative and while some can be zero, at least one should be positive. The weighted average calculator supports weights expressed on the scale of zero to one (0.1), percentages (0%.100%), ranks, and others (1,3,5, etc.). A prominent example of using a weigted mean is in finance where the weighted average cost of capital (WACC) is often used to give more weight to financial flows happening sooner versus those happening later in time.Īn ordinary average can be seen as a particular case of a weighted average in which all the weights are equal. An example of the latter is averaging school grades across a number of school classes with different counts of students in them. An example of the former is weighting grades for classes by the number of credits they give or their difficulty (as in weighted GPA). in ranking tasks, indices, etc.) or when there is a need to average statistical measures that come from populations of differing sizes. The weighted average is often used when preference needs to be given to certain data points due to their relatively higher importance (e.g. weighted mean, weighted arithmetic mean) is a measure of centrality in which some data points contribute differently (more or less) than others.
