1 answer

To find the range of a set of data, you subtract the minimum value from the maximum value.

From the given data set: 9, 4.5, 8, 6, 9.5, 5, 6.5, 14, 4

  1. Identify the maximum value:

    • The maximum value is 14.

  2. Identify the minimum value:

    • The minimum value is 4.

  3. Calculate the range: \[ \text{Range} = \text{Maximum} - \text{Minimum} = 14 - 4 = 10 \]

So, the value of the range for this set of data is \( \boxed{10} \).
