“How can we represent a set of vectors?”

 

Vectors are one of the most important aspects of Linear Algebra. But in order to have a true set of vectors, they must be closed under vector addition and scalar multiplication. This is known as a Vector Space and is vital for a true understanding of Linear Algebra.

“How can we flip rows and columns of a matrix?”

 

When doing Linear Algebra, there are times where we may want to flip the rows and columns. This can be accomplished through Matrix Transposition. A matrix that has undergone transposition is known as a transposed matrix. If we multiply the transposed matrix by the original matrix then we arrive at the identity matrix.

“What happens when we have a matrix where everything outside of the diagonal is zero?”

 

Matrices come in all shapes and sizes. But some of them are very special indeed. One of these include matrices where everything outside of the main diagonal is zero. These very special easy to solve matrices are known as Diagonal Matrices and are great for solving equations.

“What is the difference between Probability and Statistics?”

 

In everyday talk, probability and statistics are lumped together. But in reality they are more like two sides of the same coin. Probability is the prediction of the likelihood of future events while Statistics is the analysis of the frequency of past events. Therefore, this is The Difference Between Probability and Statistics.
