Let's calculate the percentage change in enrolments for each course from 2001 to 2002 using the pie charts.
1. Commerce
- 2001: 10.30%
- 2002: 9.40%
- Change: $9.40 %-10.30 %=-0.90 %$
- Percentage change: $\(\frac{-0.90}{10.30} \times 100 \approx-8.74 %\)$
2. Technical
- 2001: 5.10%
- 2002: 14%
- Change: $\(14 %-5.10 %=8.90 %\)$
- Percentage change: $\(\frac{8.90}{5.10} \times 100 \approx 174.51 %\)$
3. Humanities
- 2001: 2%
- 2002: 6%
- Change: $\(6 %-2 %=4 %\)$
- Percentage change: $\(\frac{4}{2} \times 100=200 %\)$
4. Science
- 2001: 20%
- 2002: 10%
- Change: $\(10 %-20 %=-10 %\)$
- Percentage change: $\(\frac{-10}{20} \times 100=-50%\)$
5. Vocational
- 2001: 20%
- 2002: 17%
- Change: $\(17 %-20 %=-3 %\)$
- Percentage change: $\(\frac{-3}{20} \times 100=-15 %\)$
Conclusion
The Humanities course had the greatest percentage change in enrolments from 2001 to 2002, with a $200 %$ increase.
