• Data Visualization in Excel: Create bar charts, line charts, histograms, and scatter plots to visualize trends and patterns in data.
• Macros and Automation: Basic introduction to creating macros and automating repetitive tasks.

SQL for Data Analysts:

SQL (Structured Query Language) is an essential skill for any data analyst, as it allows you to interact with databases and extract meaningful information from large datasets. Key topics covered include:

• SQL Basics: Learn how to write queries to SELECT, INSERT, UPDATE, and DELETE data.
• Joins: Perform INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN operations to combine data from multiple tables.
• Aggregation and Grouping: Use functions like SUM, COUNT, AVG, MIN, MAX, and GROUP BY for summarizing and aggregating data.
• Subqueries and Nested Queries: Write more complex SQL queries to extract specific data.
• Data Filtering and Sorting: Use WHERE, HAVING, and ORDER BY to filter and sort data.
• SQL Case Statements: Use CASE statements to create conditional logic in SQL queries.

Python for Data Analysis:

Python is one of the most popular programming languages for data analysis. This module covers the basics of Python and key libraries used for data manipulation and analysis.

• Python Basics: Learn Python fundamentals such as variables, data types, control structures (if-else, loops), and functions.
• Data Analysis Libraries:
  • NumPy: For handling arrays and performing numerical operations.
  • Pandas: For data manipulation and analysis, including reading/writing data, handling missing data, and transforming data.
• Data Cleaning with Python: Techniques for cleaning messy data using Pandas, such as removing duplicates, handling missing values, and normalizing data.
• Data Transformation: Use Pandas to filter, sort, and aggregate data. Learn how to reshape data using melt, pivot, and groupby functions.

Exploratory Data Analysis (EDA):

EDA is a critical step in understanding the structure of the dataset, detecting outliers, and identifying patterns. In this module, students will learn how to:

• Summary Statistics: Compute measures of central tendency and dispersion.
• Data Visualization: Create various charts (e.g., bar charts, line plots, histograms, box plots, and scatter plots) to visually explore data and identify trends.
• Correlation Analysis: Use heatmaps and pair plots to visualize relationships between variables.
• Identifying Outliers: Use visual methods and statistical techniques to detect outliers in the data.

Data Visualization:

Communicating insights effectively is a crucial skill for data analysts. This module focuses on various tools and techniques for visualizing data.

• Data Storytelling Principles: Learn how to craft a narrative with data to communicate insights clearly to stakeholders.
• Creating Effective Visuals: Understand best practices for choosing the right type of chart for your data.
• Tableau: A popular data visualization tool. Learn to create dashboards, interactive reports, and presentations using Tableau.
• Power BI (optional): Introduction to Microsoft's powerful business intelligence tool for data analysis and visualization.

Business Intelligence and Reporting:

Learn how to generate insights from data and present them in a meaningful way that helps stakeholders make data-driven decisions.

• Creating Dashboards: Design interactive dashboards using Tableau or Power BI, enabling users to filter and interact with the data.
• Building Reports: Learn how to generate comprehensive reports that present your data findings effectively.
• Data Presentation: Techniques for presenting data and communicating complex insights clearly to non-technical audiences.

Introduction to Machine Learning (Optional):

For students looking to go beyond basic data analysis, this module offers a brief introduction to machine learning concepts.

• Supervised Learning: Learn the basics of machine learning models like linear regression and classification.
• Unsupervised Learning: An introduction to clustering techniques (e.g., k-Means).
• Model Evaluation: Learn how to evaluate model performance using metrics like accuracy, precision, recall, and F1-score.

2. Real-World Projects and Hands-On Practice

Throughout the course, students will engage in hands-on projects that simulate real-world data analysis scenarios. These projects allow students to apply their skills to solve business problems and build a portfolio.

Example Projects:

• Sales Data Analysis: Analyze sales data to identify trends, seasonality, and customer behavior. Use SQL to extract data from a database and Python or Excel to analyze it.
• Customer Segmentation: Use demographic and transactional data to segment customers based on purchasing behavior and lifetime value.
• Churn Analysis: Perform churn analysis for a subscription-based service to understand why customers are leaving and predict which customers are at risk of churning.
• Stock Market Analysis: Analyze stock prices over time, calculate moving averages, and develop insights into market trends.
• Survey Data Analysis: Use survey data to analyze customer satisfaction and create visual reports for decision-makers.

These projects will be valuable additions to your portfolio, helping demonstrate your practical skills to potential employers.
