To determine the relationship between daily temperature and cake sales, we use a statistical measure called the correlation coefficient. This coefficient ranges from -1 to 1, where values close to 1 indicate a strong positive relationship, values close to -1 indicate a strong negative relationship, and values around 0 indicate little or no linear relationship.
For Amélie's data:
- The correlation coefficient is approximately [tex]\(-0.197\)[/tex].
- Since this value is negative and not close to -1, it indicates a weak negative relationship.
Based on this information:
- The correlation coefficient is close to -0.2.
- We can conclude that Amélie's cake sales are negatively affected by the daily temperature.
