# Mathematics for Data Scientist

To excel in the field of data science, especially as a data scientist, I would recommend you have good command over the topics mentioned below. These are the topics from mathematics and statistics. There are many YouTube channels that you can use for this purpose. Because this is 10+2 level mathematics, and it is just a matter of revision. So I am not offering any course unless there is a specific need for some group, organization.

## Linear Algebra

1. Introduction to Linear Algebra
2. Eigenvalues And Eigenvectors
3. Calculating Eigenvalues and Eigenvectors
4. Eigen decomposition of a Matrix
5. Eigenvectors: What Are They? Intuition behind.

8. Statistical Measures (mean, mode, median, max, min)
9. Measure of dispersion (range, standard deviation, variance, covariance, correlation, error deviation)
10. Central Limit Theorem (CLT)
11. What is Regression? How it works? OLS (Ordinary Least Square), Multi-linear regression.
12. Standard Error
13. Dimensionality Reduction (PCA)
14. Parameter Properties (Bias, Consistency, Efficiency)
15. Statistical tests t-test, z-test, ANOVA test, Chi-Square test
16. Conditional Probability (Bayesian Theorem)
