A Correlation Matrix: Environmental Toxins, Housing Costs, and Asthma Rate 1 2 3 Environmental Toxins Housing Costs Asthma Rate 1. Environmental toxins 1 -0.803 0.980 2. Housing costs -0.803 1 -0.889 3. Asthma rate 0.980 -0.889 1 Correlation matrices are very useful because they summarize the relationship between multiple variables, allowing you to look at multiple relationships simultaneously. You will find a correlation matrix in most research papers. To orient yourself, first, find the correlation coefficient between environmental toxins and housing costs, which is-0.803 . Which of the following correctly describes the relationship between environmental toxins and housing costs? The calculations show a strong negative linear relationship between environmental toxins and housing costs. The calculations show a moderate negative linear relationship between environmental toxins and housing costs. The calculations show a strong positive linear relationship between environmental toxins and housing costs. The calculations show a moderate positive linear relationship between environmental toxins and housing costs. Second, find the correlation coefficient between housing costs and asthma rate, which is
