- 1. Point of inflection: f"(x)=0. A curve is convex if for all values of x, f"(x) ≥ 0 and concave if for all values of x, f"(x) ≤ 0
- 2. Skewness : A measure of a data set's asymmetry. A skewness value near 0 indicates a data set with a symmetric histogram. A skewness value greater than +1 indicates that a data set is positively skewed. A skewness value less than -1 indicates that a data set is negatively skewed.
