The bar chart indicates the number of boys and girls enrolled in sports activities in a public school, over 3 time periods approximately 20 years apart, i.e. the years 1960-61, 1980-1981, and 2000-2001. The data is measured in units of tens.
In the period from 1960-61, less than 30 girls and more than 50 boys were enrolled in sports activities. In the 1980-81 period, the number of girls enrolled in sports activities rises exponentially to nearly 50. On the other hand, there is a moderate rise in boys’ enrolment, to just over 60. Finally, in the period from 2000-01, the numbers of girls and boys enrolled in sports activities shows a slight incline to just over 50 and under 70 respectively.
Based on this chart, a comparison can be made between boys’ and girls’ enrolment in sports activities over time. For both genders, sports enrolment continues to rise over time, but at different rates. The girls’ enrolment in sports was very low in 1960-61 but shows a marked increase over time; while the boys’ enrolment started out high in 1960-61, and continued to increase over time, but at a lesser rate than the girls. By the 2000-01 period, the difference between the number of boys and girls enrolled in sports activities is much less, compared to both the 1960-61 and the 1980-81 periods.
