Range of 5, 7, 12, 15, 22.

**The reasoning** Range means the **spread** of your data — how far apart the smallest and largest values are. The formula is simple: **Range = Highest value − Lowest value** From your data: 5, 7, 12, 15, 22 - Highest value = 22 - Lowest value = 5 Range = 22 − 5 = **17** That's it! You're measuring the "distance" between the extremes. --- **Why the wrong options tempt you** - **A) 5** — This is the lowest value itself, not the range. Don't confuse the starting point with the spread. - **B) 12** — This is the middle value (median). Range has nothing to do with the center; it's about the edges. - **D) 22** — This is the highest value. Again, you need the *difference*, not just one endpoint. --- **Quick takeaway** Range = Biggest number − Smallest number. Always subtract; never just pick one extreme!
