The line graph compares four sectors in the satisfaction percentage of the staff that studied over a period of 12 years.

It clears to see that the amount of satisfaction rating fluctuated erratically in almost all colleges. The most change was seen in College C whereas College D was in contrast with a lower frequency.

In 1991, around 65% of satisfaction ratings came from College A and 50% was the start number of College B. These sectors had a significant fluctuation from 1991 to 1996, before intersecting in 1997 with 60%. After that, College A decreased steadily as opposed to a gradual rise of College B over the last six years.

There was an obvious decline in the percentage of College C in the first eight years, suddenly bounced to approximately 70% just one year later and continuously rose, while College D did not record much more changes like the former that maintained the downward trend in all period.

Thank you so much!
