“As data becomes cheaper and cheaper there are more people that want to be able to analyze and interpret that data. I see more and more that people are creating tools to accommodate folks who aren’t trained but who still want to look at data right now. While I admire the principle of this approach – we need to democratize access to data – I think it is the most dangerous way to solve the problem. … The danger with using point and click tools is that it is very hard to automate the identification of warning signs that seasoned analysts get when they have their hands in the data. These may be spurious correlation like the plot above or issues with data quality, or missing confounders, or implausible results. These things are much easier to spot when analysis is being done interactively. Point and click software is also getting better about reproducibility, but it still a major problem for many interfaces.” Jeff Leek ( October 9, 2014 )
