To choose the most appropriate r-value for a scatter plot, we need to consider the strength and direction of the correlation indicated by the plot.
- **r = -0.3** suggests a weak negative correlation.
- **r = 0.2** suggests a weak positive correlation.
- **r = 0.8** suggests a strong positive correlation.
Without the actual scatter plot, it's difficult to determine which r-value is most appropriate. However, if you are looking for an indication of strength:
- If the points in the scatter plot are closely clustered and show a clear upward trend, **r = 0.8** would be appropriate.
- If the points are somewhat scattered but showing a slight upward trend, **r = 0.2** would be fitting.
- If the points trend downwards but are still somewhat scattered, **r = -0.3** may be suitable.
Based on just the options, if the scatter plot appears to show a strong relationship in the positive direction, **r = 0.8** would be the best choice. If it’s weak or unclear, then you might choose between r = 0.2 and r = -0.3 based on the direction of the scatter plot.
- **r = -0.3** suggests a weak negative correlation.
- **r = 0.2** suggests a weak positive correlation.
- **r = 0.8** suggests a strong positive correlation.
