Question

which scatterplot shows no correlation?

Explanation:

Step1: Understand correlation

Positive correlation: points trend upwards. Negative correlation: points trend downwards. No correlation: points have no clear trend.

Step2: Analyze each scatter - plot

• First scatter - plot: Points trend upwards (positive correlation).
• Second scatter - plot: Points have a wavy, but overall no clear linear trend. Wait, no, check again. Wait, actually, the fourth scatter - plot:
• Fourth scatter - plot: Points are randomly distributed with no upward or downward linear trend.

Answer:

The fourth scatter - plot (the one on the far right) shows no correlation.
