Question

The upper limit of the class 8–9 is 9 and the lower limit of the next class 10–11 is 10. What is the correction factor for converting these inclusive classes into continuous boundaries?

Options

• 0.5

• 1

• 2

• 0.25

Answer 1

The correction factor is \[ \frac{10-9}{2} = 0.5 \]. This value is subtracted from lower limits and added to upper limits.
