which is most likely the correlation coefficient for the set of data shown?\n○ −0.91\n○ −0.35\n○ 0.35\n○ 0.91
Answer
Brief Explanations:
The data points follow a strong downward linear trend: as x increases, y decreases consistently and closely to the trend line. A negative correlation coefficient indicates a downward trend, and a value close to -1 means a strong linear relationship. -0.91 is close to -1, matching the strong negative trend, while -0.35 would indicate a weak negative trend, and positive values would indicate upward trends which do not match.
Answer:
-0.91
