In math, the range of a set of numbers is the difference between the highest and lowest values in that set, providing a measure of how spread out the data is. 

Here's a breakdown:

• Definition:
  The range is a simple measure of variability or dispersion in a dataset. 

• Calculation:
  To find the range:

  • Identify the highest value (maximum) in the set.

  • Identify the lowest value (minimum) in the set.

  • Subtract the lowest value (minimum) from the highest value (maximum).

  • Formula: Range = Maximum - Minimum

• Example:

  • Set of numbers: {2, 5, 8, 11, 14}

  • Highest value (maximum): 14

  • Lowest value (minimum): 2

  • Range: 14 - 2 = 12

• Significance:
  A larger range indicates a greater spread or variability in the data, while a smaller range suggests the data points are clustered closer together.
