- Q1[ <List of Numbers> ]
- Determines the lower quartile of the list elements.
- Example:
Q1[{1, 2, 3, 4}]yields 1.5.
- Q1[ <List of Numbers>, <List of Frequencies> ]
- Determines the lower quartile of the list elements considering the frequencies.
- Example:
Q1[{1, 2, 3, 4}, {3, 2, 4, 2}]yields 1.
Note:
GeoGebra uses the Moore & McCabe (2002) method to calculate quartiles, see http://mathworld.wolfram.com/Quartile.html
