In a scatterplot with a tight upward trend, how is the relationship described?

• A. Weak
• B. No
• C. Negative
• D. Strong positive

Answer: (D)

In a scatterplot, you read both how the points go up or down (direction) and how tightly they cluster around a line (strength). A tight upward trend means the points sit close to a rising line, so as x increases, y also increases in a consistent way with little extra scatter. That shows a strong positive linear relationship (coefficients would be near +1). If the points were more scattered, it would be a weaker relationship; if there were no discernible pattern, there would be no linear relationship; if the line sloped downward, it would be negative.
