| Statistic | Definition |
|---|---|
| Mean | Sum of all values divided by count: the arithmetic average |
| Median | Middle value when sorted; unaffected by extreme outliers |
| Mode | Most frequently occurring value(s) |
| Standard Deviation | Average distance of each value from the mean; low = tightly clustered |
| Variance | Standard deviation squared; measures spread in squared units |
| Standard Error | How precisely the sample mean estimates the population mean (SD ÷ √n) |
| Q1 / Q3 | 25th and 75th percentiles of the sorted data |
| IQR | Interquartile range = Q3 − Q1; the middle 50% spread |
| CV | Coefficient of variation = SD ÷ mean × 100%; relative variability |
