Detailed Solution & Explanation

**Step 1: Understand the concept.** When all observations are of **equal importance**, the simple Arithmetic Mean is used: xˉ=∑xin\bar{x} = \frac{\sum x_i}{n} **Step 2: When importance differs.** When different observations have **different levels of importance** (weights), the **Weighted Average** is used: xˉw=∑wixi∑wi\bar{x}_w = \frac{\sum w_i x_i}{\sum w_i} where wi\displaystyle w_i is the weight assigned to observation xi\displaystyle x_i. **Step 3: Conclusion.** The correct measure is **Weighted Average**. Hence, **Option D** is the correct answer.
