Best Data Science Courses Online

The Best Free Data Science Courses on the Internet

Data science is blossoming as a field at the moment. Popular jargon from traditional statistics to new machine learning techniques are used colloquially in both online articles and day-to-day exchanges. One of the excellent things about data science, noted by David Venturi, is that by nature the field is computer-based. Why not learn about it all for free online then? Venturi has written several articles enumerating lists of massive open online courses (MOOC) relevant to someone interested in only a single highly-ranked data science class, or a complete masters degree in data science for the more dedicated individual. One of the benefits of these courses is they are more poignant and focus on only the knowledge relevant to applying data science skills. Another perk is the nonexistent price tag, as opposed to the tens or hundreds of thousands of dollars of student loans one could thrust themselves into while pursuing a data science masters at a formal institution. Venturi explains why he left grad school to learn about data science before finishing his first semester. If nothing else, some of these courses may be useful to supplement a graduate school education.

Online Population-Based Cohort Study

An Internet Survey in a Population-Based Cohort Study

Consumption of ultra-processed foods and cancer risk: results from NutriNet-Santé prospective cohort is a web-based survey looking at the association of cancer risk and consuming ultra-processed foods in people in France who responded to a survey. Population-based cohort studies were previously done by calling people’s landlines, asking them to fill out surveys, and requesting that they drive to the clinic for a health examination.

Perhaps further epidemiological studies will be done primarily using online surveys, as the authors did in this paper. It would make epidemiological studies much less expensive and more readily available. But the validity of the results have not yet been verified.

Using the internet selects for younger people responding to the survey. This may not be representative of the larger population. But as these generations age, using the internet for data collection may be a useful tool.

The internet is an anonymous place, and it is difficult to understand the population that is being studied when using the World Wide Web as the only data collection vehicle. This may be a worth-while sacrifice for the convenience of bypassing what has historically been the most arduous part of studying the public’s health.

Typing Guide

A guide on learning how to type


Step 1: Learn technique

Step 2: Practice speed


Why?

I had no idea how to type entering medical school. My peers we’re jamming out notes on their macbook like Billy Joel after 3 bottles of red. My roommate told me about this Keybr site. It adds one letter at a time, and as you get better scores it adds more letters. It’s pretty addicting. But it doesn’t really teach you proper technique. I googled lessons, and there were a bunch of sites like How To Type that illustrates which keys to hit with which finger. So I learned and spent 30 hours in the basement of the library tapping away. This is one of the most useful skills I’ve learned in grad school. I can’t believe I went through college without learning to type. Don’t make my mistake. Be better than me.

If Our Bodies Could Talk: The Big-Data Quest to Treat Every Disease

“When Sonia Vallabh and Eric Minikel discovered that Sonia had inherited the gene for a fatal neurodegenerative disease, they quit their jobs to dedicate themselves to finding a treatment. President Obama believes that the American people may be able to help. It cost $400 million to sequence a person’s genome in 2003. Now, the cost has plummeted to around $1,000. These maps of all of the genes in our bodies are now easily and quickly attainable, along with enormous amounts of other medical data. The singular question of modern medicine is what to do with this data, and how to use it effectively, efficiently, democratically, and responsibly to improve human health.”
