Question

which scatter plot shows the strongest negative correlation between price and quantity sold?
a
b
c
d
e

Explanation:

Step1: Recall the concept of negative correlation

In a scatter - plot, a negative correlation means that as the value of one variable (price) increases, the value of the other variable (quantity sold) decreases.

Step2: Recall the concept of the strength of correlation

The strength of a correlation (positive or negative) is determined by how closely the data points follow a straight - line pattern. A stronger correlation has data points that are more tightly clustered around an imaginary straight line.

For option A, the data points are randomly scattered, indicating no correlation.
For option B, there is a negative trend, but the data points are not very tightly clustered.
For option C, the data points are randomly scattered, indicating no correlation.
For option D, there is a positive correlation (as price increases, quantity sold increases).
For option E, there is a negative correlation and the data points are tightly clustered around an imaginary straight line.

Answer:

E
