  • DNone

Detailed Solution & Explanation

**Step 1: Define Pooled Mean.** The **Pooled Mean** (or Combined Mean) is the weighted mean calculated when two or more groups are combined. It is computed as: xˉpooled=n1xˉ1+n2xˉ2+⋯+nkxˉkn1+n2+⋯+nk\bar{x}_{pooled} = \frac{n_1\bar{x}_1 + n_2\bar{x}_2 + \cdots + n_k\bar{x}_k}{n_1 + n_2 + \cdots + n_k} **Step 2: Match to the options.** The Pooled Mean is also referred to as **Grouped Mean** in some textbooks, as it combines data from different groups. Hence, **Option C** is the correct answer.
