• Reading and writing data
• Simple plotting/Control flow/Debugging/Code profiling

Reading / writing data one of the first steps to kickstarting any Data Science project. Participants will have the chance to experience first-hand how to read / write data from various sources.

• Importing Data into from Various sources
• Database Input (Connecting to database)
• Viewing Data objects - sub setting, methods
• Exporting Data to various formats

The accuracy and quality of any analysis depend on how well the data is being cleaned. Data cleaning can be used to detect and correct errors or anomalies in the data. In this module, participants will learn the art of data cleaning to enhance the quality of data.

• Cleaning of Data with Python
• Steps to Data Manipulation
• Python Tools for Data manipulation
• User Defined Functions in Python
• Stripping out extraneous information
• Normalization of Data and Data Formatting
• Important Python Packages e.g.Pandas, Numpy

Data visualization helps people see, interact, and understand data better. The right visualization can help align the understanding of various stakeholders. Participants will have the opportunity to learn how to use Python Programming to perform Data Visualization.

• Exploratory Data Analysis
• Descriptive Statistics, Frequency Tables and Summarization
• Univariate Analysis (Distribution of data & Graphical Analysis)
• Bivariate Analysis(Cross Tabs, Distributions & Relationships, Graphical Analysis)
• Creating Graphs
• Important Packages for Exploratory Analysis(NumPy Arrays, Matplotlib, Pandas and scipy.stats etc)

Statistics are being used by Data Scientists to gather, review, analyze, and draw conclusions from data. Statistics are the core of machine learning algorithms, capturing, and translating data patterns into actionable evidence.

• Basic Statistics - Measures of Central Tendencies and Variance
• Building blocks (Probability Distributions, Normal distribution, Central Limit Theorem)
• Inferential Statistics (Sampling, Concept of Hypothesis Testing)
• Statistical Methods: Z/t-tests (One sample, independent, paired), ANOVA, Correlation and Chi-square
• Statistical Methods: ANOVA
• Statistical Methods: Correlation and Chi-square

Machine learning is a field of study that gives computers the ability to learn without being programmed extensively. It applies algorithms to process the data and get trained for delivering future predictions. In this module, participants will be introduced to the key concepts of Machine Learning and how it can be easily applied using Python Programming.

• Statistical Learning vs Machine Learning
• Iteration and Evaluation
• Supervised Learning vs Unsupervised Learning
• Predictive Modelling - Data Pre-processing, Sampling, Model Building, Validation
• Concept of Overfitting and Under fitting (Bias-Variance Trade off) & Performance Metrics
• Cross ValidationTrain & Test, Bootstrapping, K-Fold validation etc

A statistical technique derived from data mining, machine learning, and predictive modeling by using data from past events to predict the future. Participants will experience first-hand how predictive analytics can be deployed using Python Programming.
