Math Problem Statement
In Exercises 1–4, tell whether x and y show a positive, a negative, or no correlation. Exercise 3: Scatter plot showing distribution of points without a clear upward or downward trend.
Solution
The scatter plot shown in Exercise 3 displays a distribution of points across different quadrants without a clear upward or downward trend. The points appear scattered randomly across the graph, indicating no consistent pattern in their arrangement along the x or y-axis. Therefore, the correct answer would be no correlation between x and y.
Would you like further details on types of correlation?
Here are some follow-up questions to explore:
- What is the difference between positive and negative correlation?
- How can you determine correlation strength from a scatter plot?
- In what scenarios might two variables have no correlation?
- How does correlation differ from causation?
- What statistical methods can you use to measure correlation?
Tip: In scatter plots, look for patterns—if points generally trend upwards (positive) or downwards (negative) along the x-axis, there’s likely a correlation. Random scatter often means no correlation.
