The provided pie charts elucidate the percentage of degree holders across six different levels of credentials in science and art working in a particular engineering company between 1980 and 2008. A key observation is that there were noticeable changes in the proportions of various qualifications over three decades and Master-Science degrees were dominated the charts.
Looking into details, in 1980, degree holders in Master-Science made up the largest share of the company at 29% followed by Ph.D-Science at 25%. Whereas, First degree-Science stood at 20% making it the third largest level in the company. Additionally, Master-Art and First degree-art represented almost similar proportions at 13% and 11% , respectively, while academic achievements in Ph.D art was the smallest share for 2% of the total.
By 2008, PH.D-Science had risen slightly from 25% to 30% becoming the joint largest percentage in engineering company alongside degrees in Master-Science remained unchanged at 29%. By contrast, First degree-Science fell from 20% to 12%, while Master-art and First degree-art declined to 12% and 10%. Last but not least, Ph.D-art grew substantially from 2% to 7%.
