Harvard Data Science Certificate Program

About Data Science

Data science is a branch of computer science dealing with capturing, processing, and analyzing data to gain new insights about the systems being studied. Data scientists deal with vast amounts of information from different sources and in different contexts, so the processing they must do is usually unique to each study, utilizing custom algorithms, artificial intelligence (AI), machine learning, and human interpretation. It’s a broad field expanding rapidly across many industries, including medicine, astronomy, meteorology, marketing, sociology, visual effects, and much more. We have brought you the bestselling professional certificate program from EDX, ‘The Harvard Data Science Certificate Program’.

•  Data Visualization Principles- You will learn general principles to guide you in developing effective data visualizations.

3. Harvard Data Science Certificate Program: Probability

Probability theory is the mathematical foundation of statistical inference which is indispensable for analyzing data affected by chance, and thus essential for data scientists.

To understand data science probability you must need the following points:

• Discrete Probability- You will learn about the basic principles of probability related to categorical data using card games as examples.
• Continuous Probability- You will learn about the basic principles of probability related to numeric and continuous data.
• Random Variables, Sampling Models, and the Central Limit Theorem- You will learn about random variables numeric outcomes resulting from random processes, and the Central Limit Theorem, which applies to large sample sizes.
• The Big Short- You will learn how interest rates are determined.

4. Harvard Data Science Certificate Program: Inference and Modeling

Statistical inference and modeling are indispensable for analyzing data affected by chance, and thus essential for data scientists. In this course, you will learn these key concepts through a motivating case study on election forecasting.

In this course you will be able to learn the below points:

•  Parameters and Estimates- You will learn how to estimate population parameters.
• The Central Limit Theorem in Practice- You will be relevant to the central limit theorem to assess how close a sample estimate is to the population parameter of interest.
• Confidence Intervals and p-Values- You will learn how to calculate confidence intervals and learn about the relationship between confidence intervals and p-values.
• Statistical Models- You will learn about statistical models in the context of election forecasting.
• Bayesian Statistics- You will learn about Bayesian statistics by looking at examples from rare disease diagnosis and baseball.
• Election Forecasting- You will learn about election forecasting, building on what you’ve learned in the previous sections about statistical modeling and Bayesian statistics.
• Association Tests- You will learn how to use association and chi-squared tests to perform inference for binary, categorical, and ordinal data through an example looking at research funding rates.

5. Harvard Data Science Certificate Program: Productivity Tools

A typical data analysis project may involve several parts, each including several data files and different scripts with code. Keeping all these organized can be challenging.

In this Harvard Data Science Certificate Program, you will able to learn:

• Installing Software- You will learn how to install R, R Studio, git, create a GitHub account, and connect these tools to each other
• Unix- You will learn the basics of the file system, the terminal, and Unix commands and conceptually how these commands work within your filesystem
• Reproducible Reports- You will learn the tools to create beautiful and easy to edit data science reports.

• Model Fitting and Recommendation Systems- In this course, you will learn how to apply machine learning algorithms.

9. Harvard Data Science Certificate Program Capstone Project

This course is very different from the previous courses in the series. Unlike the rest of the courses in the Professional Certificate Program, you will receive much less guidance from the instructors. You will show what you’ve learned so far by working independently on data science projects of your own.

In this course you will able to learn:

• Movielens Project (all learners)- In this course, open to all learners, you will do a short preparatory quiz to familiarize yourself with the dataset you’ll be using and then complete a project using a dataset from Movielens.
• Choose-Your-Own Project (Verified learners only)-in open to Verified learners only, you’ll work on your own project using a dataset of your choosing.

Prerequisites:

There are no prerequisites for the first course, but the later courses assume knowledge from the prior courses in the series.
