                                                    Range in Math

Range in Math can be defined as the difference between the lowest and highest numbers in a given data set.

For example, there is a group of five students in your class and they are having a race. If you are asked to find the difference between the slowest and fastest times then you would require finding the range of time durations of all five students.

There are a few steps that can be used to find the range in math.

  • The very first step is to identify the given data set.
  • Now arrange the list of numbers in order from lowest to highest.
  • Arranging the data values like this makes it much easier to find the lowest and highest numbers.
  • While finding the range we don’t use the numbers that are in between.
  • The range can be calculated by subtracting the lowest number from the highest number.
  • The difference is the range of the data set.

Quick Facts: –

  • Range in math can also mean all the output values of a particular function.
  • The rule of thumb says that the range is about four times the standard deviation. It is another measure of spread.
  • The range can tell you how spread apart a group of data values are.
