Correlation between Sale of Cold Drinks and Day Temperature

Introduction:
Correlation is a statistical measure that describes the degree of association between two variables. In this case, we are analyzing the correlation between the sale of cold drinks and day temperature.

Positive Correlation:
When two variables increase or decrease together, it is known as a positive correlation. For example, as the day temperature increases, the sale of cold drinks also increases. This indicates that people tend to buy more cold drinks on hotter days.

Negative Correlation:
When two variables move in opposite directions, it is known as negative correlation. For example, as the day temperature decreases, the sale of cold drinks decreases. This indicates that people tend to buy fewer cold drinks on colder days.

Zero Correlation:
When two variables have no relationship with each other, it is known as zero correlation. For example, the sale of cold drinks may remain constant irrespective of the day temperature. In this case, there is no correlation between the two variables.

Conclusion:
In conclusion, the correlation between the sale of cold drinks and day temperature is positive. As the day temperature increases, the sale of cold drinks also increases. This correlation can be used by businesses to predict the demand for cold drinks and plan their inventory accordingly.
