The line graph illustrates how satisfaction levels with the education systems in Australia, Japan, the U.S.A., Germany, and Brazil changed over a 20-year period, starting from 1990.
Overall, it is evident that the percentage of people satisfied with the education systems increased in Brazil, Germany, and Japan, while it decreased in the U.S.A. and Australia. Furthermore, satisfaction levels in Japan remained consistently higher throughout the period observed.
Examining the increasing data sets in more detail, it is clear that satisfaction with the education system in Japan was around 56% in 1990. By 2010, this figure had risen to 69%, marking the highest point on the chart. Similarly, the percentage of satisfied individuals in Germany and Brazil rose from 33% and 15% in 1990 to 50% and 36% in 2010, respectively. Consequently, Brazil exhibited the greatest increase in satisfaction among all the countries during this time frame.
In contrast, analyzing the data sets that experienced a decrease reveals that satisfaction with the schooling system in Australia was approximately 50% in 1990. This figure briefly increased to 59%, then fell to 43% in 2005, before remaining relatively stable. Likewise, satisfaction levels in the U.S.A. dropped from 45% in 1990 to 39% in 2010, representing the most significant decrease across all categories.
