Question
Transcribed Image Text:**Match the Linear Correlation Coefficient to the Scatter Diagram**
The objective is to match the given linear correlation coefficients (r) to the appropriate scatter diagrams. Each diagram has identical scales on the x-axis and y-axis.
**Given Correlation Coefficients:**
- (a) r = -0.946
- (b) r = -0.546
- (c) r = -0.025
- (d) r = -1
**Instructions:**
Click the icon to view the scatter diagrams. Then drag each of the r-values provided above into the corresponding area below each diagram.
**Scatter Diagrams Analysis:**
1. **First Diagram (Left to right):**
- Displays a clear negative linear trend where data points are closely packed around a downward slope.
- **Expected r-value: Close to -1 (perfect negative correlation).**
2. **Second Diagram:**
- Displays a moderate negative linear trend with more scatter around the line.
- **Expected r-value: Around -0.5 (moderate negative correlation).**
3. **Third Diagram:**
- Exhibits a strong linear negative relationship with points closely following a downward line.
- **Expected r-value: Around -0.95 (strong negative correlation).**
4. **Fourth Diagram:**
- Shows very little to no discernible trend; points are scattered randomly.
- **Expected r-value: Near zero (no correlation).**
After analyzing, drag each correlation coefficient to its respective diagram based on the strength and direction of the linear relationship displayed.
