## 1.6 Describing Numerical Distributions

### Shape

- The
**shape**of a numerical distribution relies on two factors:**symmetry**and**outliers**. - If you can draw a vertical line through some point in the distribution whereby the distribution to the left of the line looks similar to a mirror image of the distribution to the right of it, it is an
**approximately symmetrical**distribution. If this is not the case, the distribution is**asymmetric**.

Note: in some cases, you may find situations where the distribution has perfect symmetry. In these situations, you can drop the “approximately” term and refer to it simply as **symmetrical**.
