Requirements

  • Basic programming knowledge: Familiarity with programming concepts such as variables, loops, conditionals, and functions is essential. Prior experience with Python is highly beneficial but not mandatory, as long as the student has experience with another programming language.
  • Basic understanding of databases: Familiarity with the concept of databases and basic SQL (Structured Query Language) is helpful. This includes knowledge of database tables, primary and foreign keys, and basic SQL queries (e.g., SELECT, INSERT, UPDATE, DELETE).
  • Basic mathematics and statistics: A basic understanding of arithmetic operations, averages, and simple statistical concepts (e.g., mean, median, mode, standard deviation) will be useful in the data analysis and interpretation process.
  • Computer literacy: Students should be comfortable using a computer, installing software, and navigating the file system.
  • Software and tools: A computer with Python 3.x installed, a code editor (e.g., Visual Studio Code, PyCharm), and the necessary Python libraries (e.g., pandas, matplotlib, seaborn, pymysql, SQLAlchemy) is required. Instructions on installing these tools and libraries will be provided in the course.
  • Motivation and curiosity: A strong desire to learn and explore data analysis and visualization techniques, as well as the ability to think critically and ask meaningful questions about the data, is essential for success in this course.
  • Although not mandatory, the following background knowledge and experience would be advantageous for students: Experience with Python's pandas library for data manipulation and analysis. Familiarity with the matplotlib and seaborn libraries for data visualization. Prior experience working with relational databases such as MySQL, PostgreSQL, or SQLite. Basic understanding of data cleaning and preprocessing techniques.

Description

In today's data-driven world, the ability to analyze and visualize data is an increasingly sought-after skill across various industries.
