Udemy Data Science Course Content Review:
1. Intro to Data and Data Science
You will learn about what data science is in theory and learn why almost every business on the planet is looking forward to making use of data science to boost their business.
Moreover, you will learn about other things such as business intelligence, artificial intelligence, and machine learning. The video titled “Introduction to data and data science” will make you familiar with all the terminologies and buzzwords used in the field.
The second section of the course takes you through all the things used by data scientists in Probability such as Bayesian Interface, Distributions, Combinatronics along with all the basics of probability.
It is one of the courses that includes teaching all the mathematical aspects of data science. In the last subsection of this section, you will learn about how Probability is used in other fields such as statistics, finance, and data science.
Statistics is a big part of learning data science. This section starts by introducing what statistics is and how you will use it in data science by using examples.
You then proceed to cover various parts of statistics and learn advanced statistics with every topic using practical examples. There are various things this section will help you learn such as descriptive statistics and inferential statistics.
It then moves on to Hypothesis testing and how it is used in data science using an example.
4. Introduction to Python
Python is one of the most flexible languages that can be used in everything and anything including data science, general programming, and machine learning. This section of the course starts by introducing users to Python and why you should use Python and Jupyter.
It will also help you install these tools and help users understand the Jupyter dashboard. The last subsection deals with the prerequisites for coding in Jupyter and get familiar with the interface.
You will then learn about the several Data Types available in Python and how you can use Variables. The next part involves making use of basic Python Syntax followed by advanced Python Operators. You will also learn about Conditional Statements, Functions, Sequences, and Iterations.
The section ends by introducing users to Advanced Python Tools. You will learn what OOPS is, how to use modules and packages. Users will also learn about the Standard Python Library and how to import modules in Python.
5. Advanced Statistical Methods in Python
Starting with an introduction to Regression Analysis, this section proceeds and helps users learn about linear regression, multiple linear regression and ends with logistic regression.
Once you are familiar with all types of regressions, the course helps you how to use advanced statistical models using Linear regression with Sklearn, multiple linear regression with stats models.
It then proceeds to explain other advanced statistical methods such as Logistics Regression, Cluster Analysis, K-Means Clustering, and different types of clustering such as Dendrogram.
If you are new to data science, you will need to learn various mathematical topics. In case you haven’t studied engineering or mathematics, this section is designed to help you understand all the mathematical concepts used in data science such as Matrix, Scalars, Vectors, Linear Algebra, Tensor, and Geometry.
