Other measures of location
Measures of Location
- Maximum
- Minimum
- Quartiles
- Percentiles
- Deciles
Finding Medians and Quartiles
- \(Q_{1}=\frac{n}{4}\) (lower quartile)
- \(Q_{2}=\frac{n}{2}\) (median)
- \(Q_{3}=\frac{3n}{4}\) (upper quartile)
Linear Interpolation equation
- \(\frac{median - \text{Lower data bound}}{\text{upper data bound - lower data bound}}=\frac{\text{median position}-\text{lower frequency bound}}{\text{upper frequency bound}-\text{lower frequency bound}}\)
Exercise 2C
- 16 bits of data means the median is the 8.5th place. This means that the median would be 1020. The lower quartile would 1017. The upper quartile would be 1024.5.
