Degrees of Freedom – The DL on df (6-8)
This video will explain the mathematics behind why we use n -1 and what we mean by degrees of freedom. The degrees of freedom refer to how many options exist for variation in our data. Specifically, it means degrees of freedom to vary. With large samples, the degrees of freedom matter much

How do you find the degree of a polynomial
👉 Learn how to find the degree and the leading coefficient of a polynomial expression. The degree of a polynomial expression is the highest power (exponent) of the individual terms that make up the polynomial. For terms with more that one variable, the power (exponent) of the term is the s

Hierarchical Interpolative Factorization
At the 2013 SIAM Annual Meeting, Lexing Ying of Stanford University discussed some recent results on developing new factorizations for matrices obtained from discretizing differential and integral operators. A common ingredient of these new factorizations is the interpolative decomposition

How to do a One Way ANOVA by Hand (12-4)
We are going to learn about ANOVA using an example that I hope you remember from childhood. Let’s take a walk down the yellow brick road – and listen for the sounds of the dark side of the moon – to put us in the mood to conduct a one-way ANOVA by hand. This example is from the Wizard of O
