I will then take the average of my readings to ensure accurate results and reduce the effect of any inaccuracies.
Obtaining Evidence/Analysing Evidence
And Drawing Conclusions:
I have tabulated the results of the experiment so that any patterns will become more apparent and I can distinguish whether my hypothesis was correct. The concentration column in the table states the percentage of brine as opposed to water used to test each reading.

After taking these readings, I realised that although both tables 1 and 2 show a similar trend, the actual figures are very different. They vary from a resistance of 468 ohms at one reading to 235 ohms at the same concentration. Although I had been careful to keep the same brine for each reading and controlle ...
