The line chart illustrates how the number of students from three different nations who enrolled at Sheffield University change over a five-year period.
It is apparent that the enrollment of Iranian students and Turkish students grew sharply. Meanwhile, the trend of Greece students was the only one of the three that underwent a downturn from 2005 to 2009.
Iranian admissions showed steady growth throughout the period from about 40 in 2005 to over 80 in 2008, followed by a dramatic rise reaching around 160 students in 2008. Similarly, Turkish numbers increased from a low of 20 in 2005 to around 90 in 2007, then grew steadily for the remainder of the period (90 to over 120).
In contrast, numbers of Greek dropped sharply from 180 in 2005 to around 70 in 2007, then reach a plateau of 70 for 2 consecutive years (2007 to 2008), before falling again to approximately 45 students in 2009.
