Statistical Formulas
- Sample Size formula: COUNT(values, values)
- Average formula: AVERAGE(no1, no2...)
- Median formula: MEDIAN(no1, no2...)
- Mode formula: MODE(no1, no2...)
- If multiple values have the same frequency, Excel follows a top-down approach and returns the first value it encounters as the mode.
- Maximum formula: MAX(no1, no2...)
- Minimum formula: MIN(no1, no2...)
- 25th Percentile formula: PERCENTILE(array, k)
- k represents the data tile (e.g., 0.25 for the 25th percentile)
- When using PERCENTILE, the range is for baking ( unclear what this means, needs clarification)
- The notation [acb] is used for a specific range (needs clarification)
- Percentage notation: always represent as a decimal between 0 and 1, e.g., 25% is equivalent to 0.25
