Yes, the ruler, which was used to measure the length of the cord and tape, collected data that could be trusted. This is because rulers are manufactured to specifically measure the lengths of objects. Therefore, the units on the ruler are exact, which allows the person carrying out the experiment to end up with precise data.
Yes, the power pack which provided volts of electricity for the electromagnet to work, provided the experimenter with trustable data, which was the volts of electricity it was giving out. This is because the power pack allowed the experimenter to control the volts of electricity the power pack was giving out, by turning an object on the power pack. Since power packs are manufactured and are designed to specifically give …show more content…
All of the processed data collected, were also accurate, due to the fact that the pattern found in the average amount of paper clips electromagnet, made from different lengths of cord attracted, supported the hypothesis. In addition, most of the trials performed for each length of cord gave similar data, which allowed the experimenter to analyze and draw accurate conclusions from the data. However, there was one drastic difference between the data collected for 50cm of cord. For example the difference between the trials for the other four lengths of cord were generally from 1 to 3 paper clips. However, the difference between the paper clips from trial 1 and 2 for 50cm long cord, was 4 paper clips, while the difference between trial 2 and 3 was 7 paper clips. However, this was not the result of the measuring instruments not collecting precise data, as a measuring instrument was not used to count the paper clips. Instead, the experimenter had counted the amount of paper clips the electromagnet had attracted. Therefore, the data collected for trial 2 was a fluke, as it was the only piece of data out of the ordinary, and also because all of the other data collected made
