Becoming a Data Scientist: What a Data Scientist ISN’T

If you’re reading this you probably already have an inkling of what a data scientist is. Have you ever considered what a data scientist isn’t? According to Vincent Granville, author of Developing Analytic Talent: Becoming a Data Scientist, data scientists are: Not statisticians Not data analysts Not computer scientists Not software engineers Not business analysts Data scientists do have some knowledge in each of these areas but also some outside of these areas. NEITHER STATISTICIANS NOR DATA ANALYSTS: One reason the gap between statisticians and data scientists has grown over the last 15 years is that academic statisticians, who publish theoretical articles (sometimes not based on data analysis) and train statisticians, are… not statisticians anymore. Also, many statisticians think that […] Continue Reading

Normal Distribution Curve

In the orange juice problem, you’re trying to blend juices to take out variability, so is it reasonable to expect that the product you’re getting from your suppliers In the orange juice problem, you’re trying to blend juices to take out variability, so is it reasonable to expect that the product you’re getting from your suppliers won’t have variable specs? Chances are that shipment of Biondo Commune orange juice you’re getting from Egypt won’t have an exact 13 Brix/Acid ratio. That may be the expected number, but there’s probably some give around it. And oftentimes, that wiggle room can be characterized using a probability distribution. A probability distribution, loosely speaking, gives a likelihood to each possible outcome of some situation, […] Continue Reading

Be Data Smart and use data science to transform information into insight

Data Science gets thrown around in the press like it’s magic. Major retailers are predicting everything from when their customers are pregnant to when they want a new pair of Chuck Taylors. It’s a brave new world where seemingly meaningless data can be transformed into valuable insight to drive smart business decisions. But how does one exactly do data science? Do you have to hire one of these priests of the dark arts, the “data scientist,” to extract this gold from your data? Nope. Data science is little more than using straight-forward steps to process raw data into actionable insight. And in Data Smart, author and data scientist John Foreman will show you how that’s done within the familiar environment […] Continue Reading

Becoming A Data Scientist: Corporate and Association Training Programs

A few universities and other organizations have started to offer data science degrees, training, and certificates. Conferences and competitions also exist for people serious about adding credentials as data scientists. Corporate and Association Training Programs, Conferences and Competitions Both private companies and professional organizations offer certifications or training. Here are a few of them: INFORMS (Operations Research Society): Analytics certificate Digital Analytics Association: certificate TDWI (The Data Warehousing Institute): Courses; focus is on database architecture American Statistical Association: Chartered statistician certificate Data Science Central: Data science apprenticeship International Institute for Analytics: More like a think tank. Founded by the famous Tom Davenport (visiting Harvard Professor and one of the fathers of data science) Statistics.com: Statistics courses Fees range from below […] Continue Reading

Optimization Modeling: Because That Fresh Squeezed Orange Juice Ain’t Gonna Squeeze Itself

When you were a child, perhaps there came that day when someone explained to you that Santa Claus didn’t exist, outside of men with bad rosacea dressed up at the mall. Well, today I’m going to shatter another belief: your not-from-concentrate premium orange juice was not hand squeezed. In fact, the pulp in it is probably from different oranges than the juice, and the juice has been pulled from different vats and blended according to mathematical models to ensure that each carafe you drink tastes the same as the last. Consistent taste in OJ year round isn’t something that just anyone can pull off.  Oranges aren’t in season in Florida year round. And at different times of the year, different […] Continue Reading
