TYPE	NUMBER	.     .
Guernsey	8400
Ayrshire	7200
Jersey	10800
Freshian	16400
Shahiwal	5200

1. Using a scale of 1cm to represent 4000 animals, represent the above data using a divided rectangle. 
2. State two advantages of using a divided rectangle to represent data.
3. Name three other ways through which the data above can be statistically presented.

Answer 1

Filled table

TYPE	NUMBER	.     .
Guernsey	8400	8400/48000 x 12=2.1(8400/4000 =2.1)
Ayrshire	7200	7200/48000 x 12=1.8(7200/4000=1.8)
Jersey	10800	10800/48000x12=2.7(10800/4000=2.7)
Freshian	16400	16400/48000x12=4.1(16400/4000=4.1)
Shahiwal	5200	5200/48000x12=1.3(5200/4000=1.3)

1. divided rectangle
   
2. Advantages
   • Each individual component is clearly seen
   • It allows for comparison of quantities of the various components
   • It can be used to represent a wide range of data
3. Other methods
   • Pie charts/ proportional circles
   • Bar graphs
   • Simple line graphs
