Statistics is a fascinating subject. There are many jokes about statisticians' obsession with numbers, but the subject is of vital importance in today's age of data mining.
I often got confused between mean, median and mode, but learnt an interesting concept called correlation. Two properties are said to be correlated when they increase or decrease in tandem. Due to this, we often tend to confuse between correlation and causation. Correlated properties are indeed necessary for each other, but they may not just be sufficient.
Talking about Statistics, we had a section on Probability, Permutations and Combinations. The problems always involved real-life scenarios like getting Heads or Tails five times in a row of coin flip, or chances of seating next to your favourite (girl) friend in cinema. Solving such examples was superfun.
And yet, I was dissatisfied with probability at a certain level. For example, they said chance of air crash is miniscule compared to car crash. But did this consider the fact that road traffic far outnumbers air traffic? And, even if air crash has 0.0001% chance, what was going to stop it from materializing for the flight I would be travelling on?
Of course, now I realize that mathematics doesn't work that way!
