Creating Box Plots from Raw Data
This section explains the fundamental process of constructing box plots from a given dataset. The process begins with ordering numbers and identifying key statistical measures.
Example: Using the dataset: 2, 11, 7, 5, 10, 8, 3, 14, 9, 6, 7
When ordered: 2, 3, 5, 6, 7, 7, 9, 10, 11, 14
Definition: A box plot consists of five key components: lowest value, lower quartile (LQ), median, upper quartile (UQ), and highest value.
Vocabulary:
- Lower Quartile (LQ): The middle number before the median (5)
- Median: The central value in ordered data (7)
- Upper Quartile (UQ): The middle number after the median (10)
Highlight: The box in a box plot extends from the lower quartile to the upper quartile, with a line indicating the median position.
