The graph illustrate the number of enquiries received by the Tourist Information Office in a city over a six-month period in 2011. The data is divided into three enquiry methods: in person, by telephone, and by letter/email.
At the beginning of the period, telephone and letter/email enquiries were more common, with around 900 and 750 inquiries in January, respectively. In contrast, face-to-face enquiries were the least frequent, starting at approximately 400. However, over the six months, the trend changed significantly.
The number of in-person enquiries saw a steady rise, surpassing the other two categories by March and continuing to increase sharply, reaching nearly 1,900 in June. Similarly, telephone enquiries initially fluctuated but started growing from April, reaching around 1,600 by June. On the other hand, enquiries by letter or email declined continuously, dropping to about 400 by May and remaining constant in June.
In conclusion, personal and telephone enquiries became increasingly popular, while letter email enquiries significantly decreased over the period. This suggests a shift in tourists preferences towards more direct and immediate forms of communication.
