The provided pie charts delineate the propotions of degrees with different levels of qualifications in science and art in a particular engineering company from 1980 to 2008, spanning 30 years.
Overall, there was a predominant surge in the first degree and a considerable plummet in ph.D-Art during the specified period of time. It is also worth noticed that some qualification percent remained stable throughout the given time.
In 1980, while there was merely 12% of Science graduates in first class degree, it exhibited a notable uplift of 20% in 2008. Meanwhile Ph. D in art reflected a steady decrease from 7% to just 2% by 2008, demostrating a less interest in the subject specilaization. Conversely, master in art and science showed a static trend throughout the 30 years. In 1980, Ph.D in Science with 30%, surpass other qualifications, while master degree in science with 29%, outshine other degree courses in 2008. In short, almost all the degree courses demostrated a moderate growth in the results.
