The pie charts display data about the proportions of students enrolled in specific types of courses at Salisbury College with a span of 10 years from 1984 to 2004.
Overall, the rate of face-to-face courses was dominant among remaining types, whereas the chunk of mixed-media courses was the least throughout the period.
In 1984, the share of face-to-face course, with an approximate value of 67%, was the highest among all types and remained constant for next ten years, before the trend experienced a sharp fall to roughly 40% by 2004. Similarly, the rate of correspondence courses was around 20% in 1984 and remained steady for the following ten years; afterwards, the value sharply declined to around 5% at the end of the period.
Nevertheless, the percentage of online courses, with an approximate value of 12%, was the lowest at the beginning of the period and significantly increased to approximately 35% by the end of the period.
In addition, the percentage of mixed-media courses, with a value of 18%, was second-least among all types of courses, before the rate slightly rose to roughly 20% by the end of the period.
