- [Voiceover] Algebra is a key practice in data science.…Algebra is the study of abstract quantities…and the relationships between them.…There are three kinds of algebra that are particularly…relevant to data science.…There is elementary algebra, that's the kind we all…learned, that's using calculating individual values,…you multiply this, you add that.…There is linear algebra also known as matrix algebra.…This is at the core most of the calculations of statistical…procedures, and then there is systems of linear equations.…
These are critical to linear algebra and also to the…practice of optimization which we'll take a closer look at.…Right now I'm gonna do an example on data science salaries,…and this actually comes from real data.…I'm gonna make a particular equation that goes…salary is equal to some constant plus years,…this actually has to do with age, plus bargaining…plus hours plus an error term.…You could write it like this with abbreviations,…but it's more common to write it like this.…
Let me explain the terms that are here.…
