A Level: Data Science Using Python (A10.1-R5, NIELIT / DOEACC)

Introduction

Data science is an interdisciplinary field that uses scientific processes and various algorithms to extract knowledge and insights from data that may be structured and unstructured.
Python has gathered a lot of interest recently as a choice of language for data analysis/science. Python is a free and open-source and a general-purpose programming language that is easy to learn. Python, due to its versatility, is ideal for implementing the steps involved in data science processes.
Python is being used for web development, data analysis, artificial intelligence, and scientific computing. The three best and most important Python libraries for data science are NumPy, Pandas, and Matplotlib. NumPy and Pandas are used for analyzing and exploring data. Matplotlib is a data visualization library used for making various types of graphs depicting the analysis.

Objective

With the growth in the IT industry, there is a booming demand for skilled Data Scientists, and Python has evolved as the most preferred programming language for the same. This course will focus on fundamental python programming techniques, reading and manipulating CSV files, and the various libraries for data science.

After completing the module, the student will be able to:

• Take tabular data and clean it
• Manipulate the data
• Run basic inferential statistical analyses.
• Perform Data Analysis
• Perform Visualization of analysis
• Built a Front end GUI

Duration
120 Hours – (Theory: 48 hrs + Practical: 72 hrs)
