Question

A scatter plot contains a trend line that passes through points (2, 5) and (3, 7). Does this trend line illustrate a correlation?
A. Yes, there is a positive correlation.
B. Yes, there is a negative correlation.
C. No, there is no correlation.
D. There is not enough information.

Answer 1

Given that the scatter plot contains a trend line that passes through (2,5) and (3,7),
the slope of this line is given by:
slope,m=(7-5)/(3-2)=2/1=2
this shows a positive slope, but other than this we cannot draw any further details concerning the points such as the correlations, hence the answer is:
D. There is not enough information.
