7 Dean measures the lengths of 12 pieces of used chalk to the nearest half inch. Make a line plot to show the data. \( 2 \frac{1}{2}, 1 \frac{1}{2}, 2,1 \frac{1}{2^{\prime}} \) \( 2,1,1 \frac{1}{2}, 1 \frac{1}{2} \) \( 2, \frac{1}{2}, 1 \frac{1}{2}, 2 \frac{1}{2} \)

To create a line plot, Dean can first compile the lengths of all the chalk pieces measured to the nearest half inch. Listing out the chalk lengths gives us: - \( 1 \frac{1}{2} \) (4 times) - 1 (1 time) - 2 (3 times) - \( 2 \frac{1}{2} \) (2 times) Once you have the tally ready, draw a horizontal line and mark these lengths (e.g., 0, 1, \( 1 \frac{1}{2} \), 2, \( 2 \frac{1}{2} \)). Above each length, you place a dot (or an X) for each chalk piece you measured. Your line plot will visually summarize the lengths and their frequencies clearly and effectively! By using a line plot, you're not only organizing your data, but also making it easy to notice patterns. For example, 1.5 inches has the highest number of occurrences, making it the most common chalk length among the pieces measured. This is not just a good visual representation; it helps in analyzing and understanding trends in data collection for future projects!
