Toasta AI Explanation
Why the answer is C, and why the others tempt you.
## The reasoning The **range** is the difference between the **highest** and **lowest** values in a dataset. It tells you how "spread out" the numbers are. **Step 1:** Identify the smallest number = **5** **Step 2:** Identify the largest number = **22** **Step 3:** Calculate: Range = Largest − Smallest = 22 − 5 = **17** So the answer is **C) 17**. --- ## Why the wrong options tempt you **A) 5** — This is the *smallest value*, not the range. Don't confuse the lowest number with the spread. **B) 12** — This is the *middle value* (median), but that's a different measure entirely. **D) 22** — This is the *largest value*. Again, the range isn't just one extreme — it's the gap between both extremes. --- ## Quick takeaway **Range = Biggest − Smallest.** You're measuring the *distance* between the two ends, not picking one of them!
