which scatterplot shows no correlation?
which scatterplot shows no correlation?
Answer
Explanation:
Step1: Understand correlation concept
In a scatter - plot, positive correlation shows points forming an upward - sloping pattern, negative correlation shows a downward - sloping pattern. No correlation means points are randomly scattered.
Step2: Analyze each scatter - plot
The first scatter - plot shows an upward - sloping pattern (positive correlation), the second shows a downward - sloping pattern (negative correlation), the third shows an upward - sloping pattern (positive correlation). The fourth scatter - plot has points randomly distributed with no clear upward or downward trend.
Answer:
The fourth scatter - plot (from the left) shows no correlation.
