Question

The range of the data \(35, 12, 21, 24, 15, 7, 16, 12, 30, 32, 13, 17\) is:

• A. \(28\)
• B. \(42\)
• C. \(17\)
• D. \(21\)

Hint:

Range is the simplest measure of dispersion and is calculated by subtracting the smallest observation from the largest observation.

Answer 1

The Correct Option is A

Step 1: Identify max and min values in the data set.
Data: 35, 12, 21, 24, 15, 7, 16, 12, 30, 32, 13, 17. Maximum \(=35\), Minimum \(=7\).

Step 2: Compute range.
Range \(=35-7=28\). \[ \boxed{28} \]
