Question

match each scatterplot shown below with one of the four specified correlations. a. 0.18 b. 0.09 c. -0.56 d. 0.86

Explanation:

Step1: Analyze correlation nature

Positive correlation means points generally trend upwards from left - to - right, negative correlation means points trend downwards. The closer the absolute value of the correlation coefficient is to 1, the stronger the linear relationship.

Step2: Observe scatterplot

The scatterplot shows a weak positive linear relationship. Values close to 0 indicate weak relationships, and positive values indicate an upward trend. Among the given values, 0.18 and 0.09 are positive and close to 0, but 0.18 shows a slightly stronger linear tendency than 0.09 for the given scatterplot.

Answer:

a. 0.18
