Introduction to Data Science and Analytics

Learn the fundamentals of data science and analytics, from problem formulation through to model building and interpretation of results.

Introduction to Data Science and Analytics is aimed at the professional who wants an introduction to data science with a strong focus on business applications. By the end of the course, beginners will be capable of building, tuning and deploying regression and classification models for a variety of business problems. Participants will also gain an understanding of unsupervised learning techniques and big data architecture.

Taught using a variety of open source and cloud technologies, the course teaches techniques for handling, manipulating and analyzing high volume (1m + row), high dimension business data.

Some familiarity with R or Python (in the form of self study or an online MOOC) is recommended prior to starting the course.

Who Should Attend?

This course is suitable for anyone who would like a better understanding of data science and how it can be used to make better decisions with data.


It is recommended that participants have completed an introductory R programming course or MOOC and at least one introductory statistics unit at the university level.

Data Fields

The digital marketing dataset includes information about customer demographics, product category purchased and the digital marketing channel the customer engaged with at each respective online touchpoint.

The airlines dataset includes information on domestic US flights that departed Houston in 2011. The fields include departure time, arrival time, flight number and destination location (alongside 17 other fields).

Data Format

The data is provided to participants in unstructured .dat format. Participants are taught how to import the dataset into Excel and convert the .dat file into an .xlsx file.
