Question
### Analyzing Distribution Shapes **Dataset (in Stem-and-Leaf Plot format):** | Stem (Tens) | Leaf (Units) | |-------------|--------------| | 1 | 5 | | 2 | | | 3 | | | 4 | 7 | | 5 | | | 6 | 2 | | 7 | 51 | | 8 | 64 | | 9 | 362 | | 10 | 4510 | | 11 | 2 | | 12 | | | 13 | 7 | *Note: In this stem-and-leaf plot, each "stem" represents the tens digit, and each "leaf" represents the units digit. For instance, the number 51 is represented as stem 5 and leaf 1.* where `7|2 = 72 students` **Question:** What is the shape of the distribution? **Answer Choices:** - Symmetric - Skewed Right - Skewed Left - Heavily Skewed to the Right **Explanation:** To determine the shape of the distribution, observe the concentration of values within the stem-and-leaf plot. The distribution here shows higher frequency in the middle range with fewer values at the extremes, indicating how the data is spread. - **Symmetric:** The distribution is evenly spread on both sides. - **Skewed Right:** The tail on the right side (higher value side) is longer. - **Skewed Left:** The tail on the left side (lower value side) is longer. - **Heavily Skewed to the Right:** The distribution has a very long right tail with most values concentrated on the lower end. For this specific data, the distribution appears to be concentrated towards the middle right with fewer values on the extreme left, indicating a rightward skew. **Recommendation:** Select "Skewed Right" based on the given data visualization.
