What You Will Learn in This Data Science Course
Module 1: Introduction to Data Science
What is Data Science and Why Is It Important?
In this foundational module, you’ll explore the core concepts of data science. You'll learn what data science is, why it matters, and how it is transforming industries like healthcare, finance, retail, and more. The module emphasizes the business impact of data and how data-driven decisions are reshaping the competitive landscape.
Data science combines computer science, statistics, mathematics, and domain expertise to uncover actionable insights from raw data. You’ll understand how data scientists ask questions, form hypotheses, test models, and ultimately influence business outcomes.
Data Science Lifecycle: From Data Collection to Insight Generation
Next, you’ll be introduced to the data science lifecycle — the structured process data professionals follow:
- Problem Identification
 - Data Collection
 - Data Cleaning & Preparation
 - Exploratory Data Analysis (EDA)
 - Model Building
 - Model Evaluation
 - Deployment
 - Insight Generation & Communication
 
Each of these steps will be revisited and practiced throughout the course.
Introduction to the Role of Data Visualization
Finally, the module introduces the importance of data visualization in the data science process. Without effective visuals, even the most powerful insights can go unnoticed. You’ll explore real-world examples where visualization played a crucial role in driving decisions.
Module 2: Python Essentials for Data Science
Python is the go-to language for data science, and this module ensures you’re proficient in it.
Core Python Programming for Data Science
You’ll start with the fundamentals — variables, control flow, functions, loops, and object-oriented programming — tailored for data-driven tasks.
Working with Data Structures and Libraries
Learn how to handle large datasets efficiently using Pandas for data manipulation and NumPy for numerical operations. You’ll work with Series, DataFrames, arrays, and understand indexing, slicing, and transformations.
Writing Clean and Efficient Code
Good code is reusable and readable. You’ll learn best practices in writing Pythonic code, including PEP8 formatting, using list comprehensions, and modular programming — skills crucial for collaborative analytics projects.
Module 3: Data Acquisition and Preparation
Data is messy — and cleaning it is one of the most important and time-consuming tasks in any project.
Importing/Exporting Datasets
You’ll learn how to load data from multiple sources: CSV files, Excel, SQL databases, JSON files, and even APIs. You'll also practice writing output data for reporting and dashboarding.
Data Cleaning, Handling Missing Values, and Data Transformation
Master techniques to detect and handle:
- Null or missing values
 - Duplicate records
 - Incorrect data types
 - Outliers
 
This prepares your data for accurate analysis and visualization.
Preparing Data for Visualization
Finally, you’ll reshape and format your data for visual platforms — converting long to wide formats, categorizing variables, and optimizing date-time fields for plotting.
Module 4: Statistics and Mathematics for Visualization
Before you can visualize insights, you need to understand the math behind them.
Descriptive and Inferential Statistics
You’ll begin with descriptive statistics (mean, median, mode, standard deviation) and move on to inferential statistics (confidence intervals, z-tests, t-tests). This helps you understand population-level patterns from samples.
Probability Distributions and Hypothesis Testing
You’ll dive into probability theory — including binomial, normal, and Poisson distributions — and practice hypothesis testing with real data. This gives statistical validity to your visualizations.
Basics of Linear Algebra and Calculus for Data Plotting
Get a basic grasp of linear algebra (vectors, matrices) and calculus concepts (gradients, derivatives) used in data transformations and optimization, especially relevant for advanced charting and machine learning.
Module 5: Data Visualization with Python
Learn to tell compelling stories using powerful Python visualization libraries.
Introduction to Data Visualization Principles
Understand the principles of good data visualization — clarity, simplicity, accuracy, and storytelling. Learn how color, scale, layout, and design impact user perception.
Matplotlib: Creating Static Charts
Start with Matplotlib, the foundational library for creating line plots, bar charts, scatter plots, histograms, and more. Learn to customize fonts, colors, labels, and legends.
Seaborn: Advanced Statistical Plots
Use Seaborn to generate aesthetically pleasing statistical plots like boxplots, violin plots, heatmaps, and pair plots — essential for quick insights during exploratory data analysis.
Plotly: Interactive Visualizations for the Web
Create interactive dashboards with Plotly, including hover effects, dynamic filters, sliders, and responsive charts. These visuals can be embedded in web applications or shared with stakeholders.
Module 6: Tableau for Data Science
This module introduces Tableau, a leader in business intelligence platforms.
Connecting Data Sources
Learn to connect Tableau to various data sources — spreadsheets, SQL databases, cloud data warehouses (like Google BigQuery or Amazon Redshift).
Building Dashboards and Storyboards
Design dashboards that combine multiple charts and KPIs in one view, and use storyboards to walk users through a narrative using visuals.
Filters, Actions, and Interactivity
Add depth and control to your dashboards using filters, parameters, calculated fields, and dashboard actions (like highlighting, navigation, or drill-down).
Creating Business-Focused Reports
Translate complex data into business-friendly reports, customized for marketing, sales, operations, or executive stakeholders.
Module 7: Advanced Visual Analytics
Take your visualizations beyond the basics with advanced techniques.
Time Series Visualization
Learn to work with time-based data, including trend analysis, moving averages, forecasting, and seasonal decomposition using line and area charts.
Geo-Spatial Data Visualization
Plot geographical data using maps — choropleths, scatter maps, and custom geo-boundaries — to visualize location-based insights like regional sales or population density.
Heatmaps, Treemaps, and Network Graphs
- Heatmaps: For correlation matrices or density visualization.
 - Treemaps: To show part-to-whole relationships.
 - Network graphs: To represent relationships in social media, supply chains, or web traffic.
 
These complex visuals help communicate layered, multi-dimensional insights.
Module 8: Machine Learning and Visualization
Bridge the gap between machine learning models and interpretability.
Visualizing Model Performance Metrics
Learn to visually evaluate models using tools like:
- Accuracy vs. loss curves
 - Learning curves
 - Cross-validation scores
 
Confusion Matrix, ROC Curves, Feature Importance Charts
Use visual tools to interpret model performance:
- Confusion matrices for classification models
