Question

which graph shows a negative correlation?

Explanation:

Step1: Recall negative correlation

Negative correlation means as \( x \) increases, \( y \) tends to decrease.

Step2: Analyze first graph

In the first graph, as \( x \) increases, \( y \) values don't show a clear decreasing trend (some increase, some stay).

Step3: Analyze second graph

In the second graph, as \( x \) increases, the \( y \) values generally decrease (from higher to lower as \( x \) moves right).

Answer:

The Middle Graph (assuming the second graph is the middle one, but based on the description, the lower graph with \( x \) and \( y \) axes where as \( x \) increases \( y \) decreases) shows negative correlation. Wait, actually, looking at the two graphs: the first has points with no clear negative trend, the second (lower) has a trend where as \( x \) increases, \( y \) decreases. So the lower graph (the second one presented) shows negative correlation.
