Math Problem Statement
Solution
The graph shows a clear upward trend where the values of increase as increases. This indicates a positive relationship. Moreover, the points are closely clustered around a straight line, which suggests a strong positive relationship.
The correct answer is:
c. Strong Positive
Would you like a detailed explanation of the reasoning? Here are some related questions to expand your understanding:
- What are the characteristics of a "strong positive" relationship in a graph?
- How does the slope of the line in a scatterplot indicate the type of relationship?
- What are examples of weak versus strong positive correlations?
- How can you mathematically calculate the strength of a relationship, e.g., using correlation coefficients?
- How does understanding correlation help in real-world data analysis?
Tip: When evaluating scatterplots, pay attention to the spread of points and the direction of their trend to determine both the strength and type of relationship.
