A horror story from the era of robots — An old friend from high school, K*, works as a data analyst for a technical services division in her company, mostly handling monthly KPI reporting and data analysis on topical issues (requested by her manager), but because she had prior experience with software development, she was the first person her…

Time to put this to rest, statistically. The trolley problem goes: a trolley is coming down a set of tracks on which five people are tied. You are standing by the lever that gives you control to re-route the trolley to a parallel track, where it will only kill one…

A follow up to yesterday’s infographic: Hani’s career trajectory within exid is actually very interesting to look at. A quick background on the group: despite debuting in 2012, EXID stayed out of the limelight until 2014, when a fancam of Hani dancing to a single from the mini "Up & Down" went viral. Prior to that, Hani had a somewhat lower vocal presence in EXID’s songs, not as prominent as LE or Solji. After the fancam, however, her presence has become more prominent within the group.

The ever critical voice inside of me, however, is curious to find out if this same narrow gap persists between men and women across the age groups.

Following my recent post regarding tall buildings and skyscrapers, my friend Kaizz asked me to research into a long-running curiosity of his: what is the threshold delineating the definitions of a mountain and a hill? When is a mountain a mountain, and when is a hill a hill? Kaizz’s question…

An interesting discussion broke out between myself and a colleague earlier today. He was wondering if Jollibee Plaza, Ortigas, our office building, classified as a skyscraper or just a really tall building. (Why he would ask me, a Statistician, baffles me as well.) Standing from the penthouse floor of our…

I’ve been thinking about permutations lately. Of course, my major being Statistics, there probably doesn’t seem to be anything strange there. But I haven’t been thinking about it for purely Mathematical reasons. A Permutation is essentially an arrangement. The mathematical notion revolves around the idea of taking elements from a…
