,1 Some students are testing the stretch of elastic bands made from different types
of rubber.
An elastic band is hung onto a stand as shown in the diagram.
a They repeat the test for each elastic band.
Explain why it is important to take repeat readings.

b The student changes the type of rubber for every experiment. She knows
that to make it a fair test she must keep everything else the same.
Suggest one thing that must be kept the same, and explain why keeping
it the same makes the test fair.

, c The results of these tests for two elastic bands, A and B, are shown in
the graph.
i The graph for band B shows a correlation between two factors.
Complete the sentence that describes the correlation.
As ……………………………increases,
………………………………………….increases.

ii Here are three statements about the tests.
Use the graph to find out if they are true or false or you cannot tell.
Put ticks () in the three correct boxes.
True False Cannot
tell
With weights less than 8 N, band A
stretches 13% for each 1 N added.
With weights less than 8 N, band A
stretches twice as much as band B.
If 20 N weights are hung on the
bands, band B is longer than band A.
