Oranges

Measuring is about making a comparison between what is being measured and a suitable measurement unit. Central to the development of measuring skills is lots of practical measuring experience. Also important is the reality that measurement is never exact.

Required Resource Materials:

• Oranges
• Measuring equipment including; rulers, scales, measuring jugs.

Activity: Complete the questions below:

1. How can you measure an orange? (there will be multiple answers for this, list as many as you can think of). Think of the attributes of an orange eg juice.

You can measure an orange with:

• Tape measure
• Scale
• Ruler (for the heights)
• Measuring jug for the juice

2. Choose two of these attributes of an orange to measure and carry out the task. Write up a proposal for your investigation, including details on:

• Attribute being measured
• Equipment required
• Method (step by step)
• How will you present your results?
• Write up your results

The two attributes we choose were the skin and the juice.

mean,median,mode and range prove it.

mean:
Example: 5 4 8 2 1
1)Add up all the numbers.
5+4+8+2+1=20
2)now count up all the numbers there are.
there is 5 numbers.
3)divide 20 by 5 and that's your answer.
20 divided by 5 =4

median:
Example: 9 7 2 6 4 
1)order the row of numbers from smallest to largest.
2 4 6 7 9
2)the number in the middle of all the numbers in the answer.
2 4 6 7 9


Mode:
Example: 2 11 4 31 11
1)the number that is the most repeated in the row of numbers is the answer.
2 11 4 31 11

Range:
Example 2 4 7 10 31
1)first you look for the smallest number and then the largest.
2 4 7 10 31
2) you now minus 2 out of 31 and that's your answer.
