Probability and Statistics Box Plots

🎬 Video Tutorial

  • (0:01) What is a Box Plot?: A box plot visually represents data distribution through five key values: minimum, lower quartile (Q1), median (Q2), upper quartile (Q3), and maximum.
  • (2:29) Calculating the Range: The range is the difference between the maximum and minimum values, showing the total spread of the data.
  • (2:42) Interquartile Range (IQR): The IQR is Q3 minus Q1, measuring the spread of the middle 50% of data. A smaller IQR suggests more consistency, while a larger IQR indicates greater spread and variability.
