Question
### Scatter Plot Analysis Shown below are the scatter plots for four different data sets. **Answer the questions that follow. The same response may be the correct answer for more than one question.** #### Scatter Plots **Figure 1** - Both axes range from 0 to 11. - The plot shows a downward trend, indicating a negative relationship between the two variables. - The points are not perfectly linear, but there is a discernible negative correlation. **Figure 2** - Both axes range from 0 to 11. - The plot shows an upward curve, suggesting a non-linear relationship. - The points tend to increase together, but not in a perfectly straight line. **Figure 3** - Both axes range from 0 to 11. - The plot shows an almost perfect upward linear trend. - The points form a near-perfect line from the bottom-left to the top-right, indicating a strong positive correlation. **Figure 4** - Both axes range from 0 to 11. - The plot shows a downward trend, similar to Figure 1, but with more scatter. - There is a negative correlation, but the relationship is not perfectly linear. #### Questions: 1. **Which data set has an apparent negative, but not perfect, linear relationship between its two variables?** - Options: Choose from Figure 1, Figure 2, Figure 3, or Figure 4. 2. **For which data set does the correlation coefficient \( r \) appear to be equal to 1?** - Options: Choose from Figure 1, Figure 2, Figure 3, or Figure 4. 3. **Which data set indicates the strongest linear relationship between its two variables?** - Options: Choose from Figure 1, Figure 2, Figure 3, or Figure 4. **[Dropdown menus are provided for each question for the user to select the appropriate figure number.]**
