The bar and line chart illustrate bathing suit sales (in hundred thousand US dollars) and average temperatures (in Fahrenheit) in New York City from January to June 2012.
Overall, sales and temperature exhibit a strong positive correlation in the first four months, with higher temperatures driving increased revenue. However, after reaching a peak in April, sales decline significantly, despite continued temperature growth.
In January, sales stood at $100,000, with an average temperature of 35F. Sales remained relatively low in February, despite a slight temperature increase. However, as temperatures rose to 45F in March, sales climbed to approximately $160,000. April experienced the highest sales, exceeding $300,000, as temperatures reached 55F.
Surprisingly, May and June show a sharp decline in revenue, despite continued warming. Sales fell to $100,000 in May, even though temperatures increased to 60F. By June, when temperatures peaked at nearly 70F, sales dropped below $50,000, suggesting that external factors, such as seasonal purchasing trends, influenced demand.
In summary, while temperature plays a key role in driving sales, it is not the sole factor, as evidenced by the dramatic decline in May and June despite rising temperatures.
