But it’s more important to understand the principles of calculus—where you’re measuring the change in small discrete or small continuous events.

More generally, unless we know better we can expect to have shown up precisely halfway into the duration of any given phenomenon.*

Means, medians, and standard deviations are examples of descriptive statistics. They are often useful, but not very interesting from a statistical or mathematical perspective. Inferential

Most textbooks pair the topic with basic statistics, because statistics requires probabilistic thinking.

It also entails understanding something very specific: a situation (in its broadest sense, be it mental, physical, or something as un-situation-like as an empty room) is inherently dynamic. And you, by the very action of entering into it, shift it from what it was before your arrival to something altogether different.
