Variance
Summary
The variance of a random variable is the expected squared distance between the variable and its mean. It measures how widely the values spread around the mean. The node variance gives the precise definition.
What this node needs for W2
- edge instance_of in: at least two examples (0 of 2)
- edge not_instance_of in: at least one non-example (0 of 1)
- edge specializes both: the more general notions and the special cases (0 of 1)
The writing levels say how complete the text of a node is. They do not measure its truth.
