Hogwarts Electives - The following scenario is fictional and is based on the Harry Potter books and movies. All third-year students at Hogwarts must take at least one elective subject. The most popular three elective subjects are Care of Magical Creatures (COMC), Ancient Runes, and Divination. Using historical data, we have determined the number of students enrolled in these three subjects from Gryffindor, Ravenclaw, Hufflepuff, and Slytherin houses during their third year at Hogwarts over the past 50 years. The (fictional) data is summarized in the two mosaic plots below. House Elective Gindor Hulpu Ravenclw Sytherin COMC Runes Divinaton Use the mosaic plots to answer the following questions: 1. Which house has the most students? Hufflepuff v 2. Which elective subject has the most students? COMC

**Educational Exercise on Data Interpretation** This educational module focuses on interpreting data related to student enrollment in various houses and elective subjects. Below are the questions and available options for each, followed by a targeted question about the relationship between elective subjects and houses based on provided mosaic plots. **Questions:** 3. **Among the 4 houses, which has the highest proportion of Runes students?** - Answer options: - **Dropdown Menu Selection**: Griffindor 4. **Among the 3 elective subjects, which has the lowest proportion of students in the Ravenclaw house?** - Answer options: - **Dropdown Menu Selection**: Runes 5. **Based on these mosaic plots, does there appear to be a relationship between the elective subject and house? Select Yes or No and a reason for your choice.** - Answer options: - **Dropdown Menu Selection**: - Yes - **Justification:** - Students can take more than one elective subject, so the data is not reliable. - The proportion of students in each elective course across houses is nearly the same. - The proportion of students in each elective course across houses is clearly different. **Graphs/Diagrams:** The provided questions reference mosaic plots, which are typically rectangular graphical representations that display the relationship between categorical variables. Each section in the mosaic plot represents the proportion of data points for a combination of categories. For example, in this case, the mosaic plots could illustrate the distribution of students across different houses and elective subjects. Larger sections indicate a higher proportion of students for that specific combination, while smaller sections indicate fewer students. Note: You can earn 8 additional points for submitting all three answers correctly. --- The questions are designed to enhance data interpretation skills by understanding the distribution and relationships within categorical data, as visualized through mosaic plots.

### Hogwarts Electives *The following scenario is fictional and is based on the **Harry Potter** books and movies.* --- All third-year students at Hogwarts must take at least one elective subject. The most popular three elective subjects are Care of Magical Creatures (CoMC), Ancient Runes, and Divination. Using historical data, we have determined the number of students enrolled in these three subjects from Gryffindor, Ravenclaw, Hufflepuff, and Slytherin houses during their third year at Hogwarts over the past 50 years. The (fictional) data is summarized in the two mosaic plots below. ![Mosaic Plots](image_link) #### Explanation of Mosaic Plots The mosaic plots visualize the distribution of students by house and elective subjects: 1. **Left Mosaic Plot**: - **X-axis** represents the four Hogwarts houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. - **Y-axis** represents the three elective subjects: CoMC, Runes, and Divination. - Each segment's area is proportional to the number of students in that category. 2. **Right Mosaic Plot**: - **X-axis** represents the three elective subjects: CoMC, Runes, and Divination. - **Y-axis** represents the four Hogwarts houses: Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. - Each segment's area is proportional to the number of students in that category. #### Questions Use the mosaic plots to answer the following questions: 1. **Which house has the most students?** - **Hufflepuff** 2. **Which elective subject has the most students?** - **CoMC**
