which scatterplot has a correlation coefficient closest to r = -1?
which scatterplot has a correlation coefficient closest to r = -1?
Answer
Explanation:
Step1: Understand correlation coefficient
The correlation coefficient $r = - 1$ represents a perfect negative - linear relationship. In a scatter - plot with $r=-1$, the points lie exactly on a straight line with a negative slope.
Step2: Analyze scatter - plots
We need to look for a scatter - plot where the points seem to form a straight line with a negative slope. Points in a scatter - plot with $r$ close to $-1$ will have a strong negative linear trend.
Answer:
We cannot determine the answer as only partial scatter - plots are shown in the image. If there were a scatter - plot with points forming a clear downward - sloping straight line, that would be the one with a correlation coefficient closest to $r=-1$.
