**Skewness** is a measure of the asymmetry of a dataset or distribution. This value can be positive or negative. A negative skew typically indicates that the *tail* is on the left side of the distribution. A positive value typically indicates that the tail is on the right.

**Kurtosis** is simply a measure of the “tailedness” of a dataset or distribution. The kurtosis formula used by this calculator is identical to the formula used in Excel, which finds what is known as *excess kurtosis*.
