For those of us who consider ourselves “efficient thinkers” (outsiders might use the term “lazy”), here is a low-effort way of comparing the central tendencies between groups WITHOUT using any hypothesis test functions! I used a [...]

Rob Slazas is not just a statistics guru; he also uses MATLAB to do everyday tasks. Today he shares some of his tricks using the Textscan command!

I was browsing the real estate listings the other day, and came across a roadblock. All the data I could ever want was readily available, but scattered in [...]
