Data Analysis:


1. Data Science: R Basics- Harvard University

This course will introduce you to the basics of R programming and is first on the list of online research courses. You can better retain R when you learn it to solve a specific problem, so you’ll use a real-world dataset about crime in the United States. You will learn the R skills needed to answer essential questions about differences in crime across the different states. You’ll learn how to apply general programming features like “if-else,” and “for loop” commands, and how to wrangle, analyze and visualize data.

Rather than covering every R skill you might need, you’ll build a strong foundation to prepare you for the more in-depth courses later in the series, where we cover concepts like probability, inference, regression, and machine learning. The demand for skilled data science practitioners is rapidly growing, and this series prepares you to tackle real-world data analysis challenges.

Course Highlights:

  • Basic R syntax
  • Foundational R programming concepts such as data types, vectors arithmetic, and indexing
  • How to perform operations in R including sorting, data wrangling using dplyr, and making plots

Course Duration: 8 weeks (1-2 hours/week)

2. Statistics and R- Harvard University

This course teaches the R programming language in the context of statistical data and statistical analysis in the life sciences. We will learn the basics of statistical inference in order to understand and compute p-values and confidence intervals, all while analyzing data with R code. We provide R programming examples in a way that will help make the connection between concepts and implementation.

Problem sets requiring R programming will be used to test understanding and ability to implement basic data analyses. We will use visualization techniques to explore new data sets and determine the most appropriate approach. We will describe robust statistical techniques as alternatives when data do not fit the assumptions required by the standard approaches. By using R scripts to analyze data, you will learn the basics of conducting reproducible research.

Course Highlights:

  • Random variables
  • Distributions
  • Inference: p-values and confidence intervals
  • Exploratory Data Analysis
  • Non-parametric statistics

Course Duration: 4 weeks (2-4 hours/week)

3. Data Science: Data Wrangling- Harvard University

This course covers several standard steps of the data wrangling process like importing data into R, tidying data, string processing, HTML parsing, working with dates and times, and text mining. Rarely are all these wrangling steps necessary in a single analysis, but a data scientist will likely face them all at some point. Very rarely is data easily accessible in a data science project. It’s more likely for the data to be in a file, a database, or extracted from documents such as web pages, tweets, or PDFs. In these cases, the first step is to import the data into R and tidy the data, using the tidyverse package. The steps that convert data from its raw form to the tidy form are called data wrangling.

Course Highlights:

  • Importing data into R from different file formats
  • Web scraping
  • How to tidy data using the tidy verse to better facilitate analysis
  • String processing with regular expressions (regex)
  • Wrangling data using dplyr
  • How to work with dates and times as file formats
  • Text mining

4. Data Science: Probability- Harvard University

In this course, part of our Professional Certificate Program in Data Science, you will learn valuable concepts in probability theory. The motivation for this course is the circumstances surrounding the financial crisis of 2007-2008. Part of what caused this financial crisis was that the risk of some securities sold by financial institutions was underestimated. To begin to understand this very complicated event, we need to understand the basics of 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.

Course Highlights:

  • Important concepts in probability theory including random variables and independence
  • How to perform a Monte Carlo simulation
  • The meaning of expected values and standard errors and how to compute them in R
  • The Importance of the Central Limit Theorem

5. Data Science: Linear Regression- Harvard University

Linear regression is commonly used to quantify the relationship between two or more variables. It is also used to adjust for confounding. This course is fifth on the list of online research courses and covers how to implement linear regression and adjust for confounding in practice using R. In data science applications, it is very common to be interested in the relationship between two or more variables. We will also examine confounding, where extraneous variables affect the relationship between two or more other variables, leading to spurious associations. Linear regression is a powerful technique for removing confounders, but it is not a magical process. It is essential to understand when it is appropriate to use, and this course will teach you when to apply this technique.

Course Highlights:

  • How linear regression was originally developed by Galton
  • What is confounding and how to detect it
  • How to examine the relationships between variables by implementing linear regression in R

Course Duration: 8 weeks (1-2 hours/week)

You will learn concepts necessary to define estimates and margins of errors and learn how you can use these to make predictions relatively well and also provide an estimate of the precision of your forecast.

Course Highlights:

  • The concepts necessary to define estimates and margins of errors of populations, parameters, estimates and standard errors in order to make predictions about data

The use of Excel is widespread in the industry. It is a very powerful data analysis tool and almost all big and small businesses use Excel in their day-to-day functioning. This is an introductory course in the use of Excel and is designed to give you a working knowledge of Excel with the aim of getting to use it for more advanced topics in Business Statistics later. The course is designed keeping in mind two kinds of learners – those who have very little functional knowledge of Excel and those who use Excel regularly but at a peripheral level and wish to enhance their skills.

The course takes you from basic operations such as reading data into Excel using various data formats, and organizing and manipulating data, to some of the more advanced functionality of Excel. All along, Excel functionality is introduced using easy-to-understand examples which are demonstrated in a way that learners can become comfortable in understanding and applying them.
