Why do scientist use table and graph in presenting their data or experiment?

While doing the experiment we can assume many different outcomes. Like for example when you play Baseball what is the guarantee that the ball wont swing to the left or the right or its trajectory wont change.

Thus scientists tabulate their findings. They then graphically represent them. The graphical representation is used to derive the conclusion for the experiment. Like for example when you are trying to derive Ohm's law you first tabulate the data and then plot a graph for the data you found out. The graph can represent:-

• A straight line confirming that the current is directly proportional to the potential difference across the conductor.
• A parabola, then the current is not directly proportional. It depends as a square of the other.

Thus with these examples we see the importance of tabulation and graph plotting. Now graph plotting is very useful for computer models.
