Math Problem Statement

What relationship does the graph represent?

Solution

The graph shows a clear upward trend where the values of yy increase as xx 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:

  1. What are the characteristics of a "strong positive" relationship in a graph?
  2. How does the slope of the line in a scatterplot indicate the type of relationship?
  3. What are examples of weak versus strong positive correlations?
  4. How can you mathematically calculate the strength of a relationship, e.g., using correlation coefficients?
  5. 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.
