If you have the Statistics Toolbox, you can calculate theskewnessandkurtosisdirectly with their respective functions. If you don’t have the Toolbox, it would be relatively easy to code those functions: skewns = @(x) (sum((x-mean(x)).^3)./length(x)) ./ (var(x,1).^1.5); ...

We can calculate a numerical value for skewness with tools such as the skewness test and excess kurtosis test. A distribution with a skewness of zero is symmetrical; any other number for skewness means that the distribution is asymmetric. That said, while we can use skewness to describe ...
In this section, you’ll learn how to identify and calculate the following variability measures:Variance Standard deviation Skewness Percentiles RangesVarianceThe sample variance quantifies the spread of the data. It shows numerically how far the data points are from the mean. You can express the ...

As pixels in a blurred image have similar neighboring pixels, we can apply a 3 x 3 Laplacian kernel on the grayscale image and then calculate the variance to detect blur. Here is the code to detect blur with OpenCV.js. If the variance is smaller than 200, the image is blurry. ...
You can calculate the mode by hand or with the help of our mode calculator below. Find the mode (by hand) To find the mode, follow these two steps: If the data for yourvariabletakes the form of numerical values, order the values from low to high. If it takes the form of categories...
