Experiment to determine the resistance of a wire - TecHKnow Wiki

In the experiment we set up a circuit and changed the length of the wire then recorded the readings for voltage and current. What would the other be?

Thanks so so much! The longer the wire, the more resistance it has.

You can never tell if you have gathered systematic error, so you can never really tell if your results are reliable. Making repeated measurements allows you to take an average, which decreases random error not systematic error. Sources of error really depend on your method; you should look at every stage in your method and see what measurements you are taking and what uncertainties are introduced at each stage.

As an example; could you measure the length of your wire with infinite precision? My general advice would be to make sure you understand the difference between systematic and random error, to look up resistivity on the internet, and to be able to define properly the words precision, reliability, and accuracy.
