Understanding Collected Data:
Collecting the data is the first step, but it is important to understand the data you have collected. Looking at the picture below, you must notice that many things are going on. Since the data collected is the voltage of a battery, the data should have a constant reading. The AAA battery used has 1.5 V, so the graph should read a constant voltage around 1.5 V.



However in the picture above, there are a few "spikes" in the graph. The first upward spike is a result of the leads bumping the battery before proper contact was made. The second spike is a result of the leads slipping from the ends of the battery for a split second causing a drop in voltage. Short, abrupt changes are expected and do not affect the overall data collection. If a "perfect" data graph was recorded, it would simply be a straight line around 1.5 V all the way across.
