Question

Find the Range and coefficent of range of the group data students = 10,20,15,25,30,25. Mark's= 0- 10,10-20, 20-30, 30-40, 40-50, 50-60​

Answer 1

Answer:

Range = Highest value - Lowest value

Range = 25-10

Range = 15

Coefficient of range = (Highest value - Lowest value)/ (Highest value + Lowest value)

Coefficient of range = (25-10) / (25+10)

Coefficient of range = (15) / (35)

Coefficient of range = 0.42
