Given a scatterplot of two numeric variables where the points form a pattern that rises from left to right, what type of relationship is represented?

• A. A negative linear relationship
• B. No relationship
• C. A positive linear relationship
• D. A non-linear relationship

Answer: (C)

Verified step by step guidance

1. Step 1: Understand what a scatterplot represents — it shows the relationship between two numeric variables by plotting data points on a coordinate plane.
2. Step 2: Observe the pattern of the points. If the points tend to rise from left to right, it indicates that as one variable increases, the other variable also increases.
3. Step 3: Recognize that when the points form a straight or roughly straight line that slopes upward, this is called a positive linear relationship.
4. Step 4: Contrast this with other types of relationships: a negative linear relationship would slope downward, no relationship would show no clear pattern, and a non-linear relationship would curve or form a pattern that is not a straight line.
5. Step 5: Conclude that the pattern described (points rising from left to right) corresponds to a positive linear relationship.
