Are there any course requirements or prerequisites?
This is a beginner friendly course so anyone can start with this immediately, however it’s expected for the students to have some basic knowledge about Python syntax
What you’ll learn
Data Manipulation with pandas
- We’ll master the pandas basics. Learn how to inspect DataFrames and perform fundamental manipulations, including sorting rows, subsetting, and adding new columns.
- You’ll calculate summary statistics on DataFrame columns, and master grouped summary statistics and pivot tables.
- Indexes are supercharged row and column names. Learn how they can be combined with slicing for powerful DataFrame subsetting.
- Learn to visualize the contents of your DataFrames, handle missing data values, and import data from and export data to CSV files.
Merging DataFrames with pandas
- You’ll learn about different techniques you can use to import multiple files into DataFrames. Having imported your data into individual DataFrames, you’ll then learn how to share information between DataFrames using their indexes.
- You’ll learn about appending and concatenating DataFrames
- You’ll explore different techniques for merging, and learn about left joins, right joins, inner joins, and outer joins, as well as when to use which. You’ll also learn about ordered merging, which is useful when you want to merge DataFrames with columns that have natural orderings, like date-time columns.
Cleaning Data in Python
- You’ll learn how to overcome some of the most common dirty data problems. You’ll convert data types, remove duplicate values and understand what are the approaches to take before making that decision.
- You’ll learn how to use regular expressions, parsing dates and where and how to use the date-time format.
- Advanced data cleaning problems, removing and imputation missing data points and using some of the powerful libraries to visualize the missing data.
Exploratory Data Analysis in Python
- The first step of almost any data project is to read the data, check for errors and special cases, and prepare data for analysis.
- You’ll learn how to represent distributions using histograms, how to identify what attributes the current data holds.
- You’ll explore relationships between variables two at a time, using scatter plots and other visualizations to extract insights from a new dataset
The Basic Probability Formula, Computing Expected Values, Frequency, Events and Their Complements. Sets and Events, union and Mutually Exclusive sets, Dependence and Independence of Sets, The Conditional Probability Formula, The Additive Rule, multiplication law, Bayes’ Law. Probability Distributions; Conditional probability, what’s the use of law of total probability and how this compliments the Bayes’ Law.
