FOUNDATIONS OF DATA SCIENCE

COURSE OBJECTIVES:

• To understand the data science fundamentals and process.

• To learn to describe the data for the data science process.

• To learn to describe the relationship between data.

• To utilize the Python libraries for Data Wrangling.

• To present and interpret data using visualization libraries in Python

UNIT I INTRODUCTION

Data Science: Benefits and uses – facets of data - Data Science Process: Overview – Defining  research goals – Retrieving data – Data preparation - Exploratory Data analysis – build the model– presenting findings and building applications - Data Mining - Data Warehousing – Basic Statistical  descriptions of Data

UNIT II DESCRIBING DATA

Types of Data - Types of Variables -Describing Data with Tables and Graphs –Describing Data  with Averages - Describing Variability - Normal Distributions and Standard (z) Scores

UNIT III DESCRIBING RELATIONSHIPS

Correlation –Scatter plots –correlation coefficient for quantitative data –computational formula for  correlation coefficient – Regression –regression line –least squares regression line – Standard  error of estimate – interpretation of r2 –multiple regression equations –regression towards the mean

UNIT IV PYTHON LIBRARIES FOR DATA WRANGLING

Basics of Numpy arrays –aggregations –computations on arrays –comparisons, masks, boolean  logic – fancy indexing – structured arrays – Data manipulation with Pandas – data indexing and  selection – operating on data – missing data – Hierarchical indexing – combining datasets – aggregation and grouping – pivot tables

UNIT V DATA VISUALIZATION

Importing Matplotlib – Line plots – Scatter plots – visualizing errors – density and contour plots – Histograms – legends – colors – subplots – text and annotation – customization – three dimensional  plotting - Geographic Data with Basemap - Visualization with Seaborn.

COURSE OUTCOMES:

At the end of this course, the students will be able to:

CO1: Define the data science process

CO2: Understand different types of data description for data science process

CO3: Gain knowledge on relationships between data

CO4: Use the Python Libraries for Data Wrangling

CO5: Apply visualization Libraries in Python to interpret and explore data
