The formula for the coefficient of range is Here, and denote
The formula for the coefficient of range is \( \frac{\text { Range }}{\boldsymbol{a}+\boldsymbol{b}} . \) Here, \( \boldsymbol{a} \) and \( \boldsymbol{b} \) denote
- A. the mean and median of the data set
- B. the maximum and the minimum value of the data set
- C. the mean and mode value of the data set
- D. the minimum and mean value of the data set
Step-by-step solution
The coefficient of range is defined as (Maximum - Minimum) / (Maximum + Minimum). Therefore, a and b in the formula Range/(a+b) represent the maximum and minimum values, respectively.
