Range, interquartile range, and standard deviation tell you how tightly clustered or widely dispersed your data points are around the center. Standard deviation is particularly powerful because it measures average distance from the mean in the original units of measurement. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
Every tool here does one job: replace a messy pile of numbers with a shorter, honest description. Average, spread, correlation — each is a summary, and each throws detail away. The real question is what got hidden in the squeeze.
Range is the difference between maximum and minimum values, interquartile range captures the spread of the middle fifty percent of data, and standard deviation measures average distance of values from the mean.
knowhere maps every concept to what it rests on and what rests on it — 0 underneath this one, 3 built on top. Each one says why, in a sentence, not as an arrow on a diagram.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
