3. which of the following graphs below shows no correlation? a. graph 1 b. graph 2 c. graph 3
Answer
Explanation:
Step1: Understand correlation concept
Positive correlation shows points clustering in an upward - sloping pattern, negative correlation in a downward - sloping pattern. No correlation has points scattered randomly.
Step2: Analyze Graph 1
The points in Graph 1 are clustered in an upward - sloping pattern, indicating a positive correlation.
Step3: Analyze Graph 2
The points in Graph 2 are clustered in a downward - sloping pattern, indicating a negative correlation.
Step4: Analyze Graph 3
The points in Graph 3 are scattered randomly with no discernible upward or downward trend.
Answer:
c. Graph 3
