The line graph delineates the volume of enquiries received by a University Admissions Office through three distinct communication methods over a six-month interval in 2021.
Overall, the data indicate a notable rise in enquiries made in person and by telephone, whereas correspondence via email experienced a marked decline throughout the observed period.
Focusing on the enquiries made in person, there was a significant increase from 200 in January to 1750 by June, demonstrating a consistent upward trajectory. Specifically, the growth was most pronounced between April and June, where the number escalated from 1100 to 1750. Conversely, enquiries conducted by telephone exhibited a more moderate yet steady growth. Beginning at 600 in January, this category peaked at 1500 enquiries by the end of June, with a notable peak occurring in May at 1200. Interestingly, a slight reduction was observed from January to February, where the figure dipped from 900 to 800 before resuming an upward trend thereafter.
Contrastingly, the number of enquiries received by letter or email displayed a declining trend throughout the study period. Starting with 100 in January, this method saw a gradual ascent to a peak of 1400 in May and then diminished to 1600 by June. This decline is particularly striking when considering the overall increasing trend in the other two channels. By June, the total enquiries via email had plummeted to approximately half of its maximum value observed in the previous months, ending at about 400. This shift indicates a significant alteration in communication preferences among prospective applicants.
