Formulas
- Mean — the arithmetic average (sum ÷ count)
- Median — the middle value of the sorted data
- Variance — population divides by n, sample divides by n − 1
- Standard deviation — the square root of the variance
- Quartiles — Tukey's method: the median of the lower and upper halves, excluding the middle value for odd-sized sets (Q1, Q3); IQR = Q3 − Q1. Excel's QUARTILE.INC may return different values.
