Range

• Range

  Range is the difference between your highest and lowest values. It is used with the median.
• How it is calculated: 

  Take the lowest value from the highest value and adding. Adding 1 enables the data to be rounding up or down to account for any margin of error.
• Strengths

  • Quick and easy to calculate
• Limitations

  It does not take central values of a data set into account, and so it can be skewed by extremely high or low values.
