Hence, the mean, variance and standard deviation of the given data are 9, 9.25, 3.041 respectively. As mentioned, variance takes the average of all the squared differences from the mean. For example, you are calculating a formula manually and you want to obtain the sum of the squares for a set of response (y) variables. If data set have small standard deviation the data points are very close to the mean. Method 2: One of the most important methods of finding the matrix inverse involves finding the minors and cofactors of elements of the given matrix. Sets, in mathematics, are an organized collection of objects and can be represented in set-builder form or roster form.Usually, sets are represented in curly braces {}, for example, A = {1,2,3,4} is a set. A square matrix in which every element except the principal diagonal elements is zero is called a Diagonal Matrix. If [A] = [a] then its determinant is given as |a| which is equal to the value enclosed in the matrix.
