So, in my previous post, I posted a mind map of my final idea- viscosity of liquids. From this, I mentioned that the dependent variable is the time taken for the marble to roll through a liquid within a test tube. This time recorded will be an indicator to the viscosity to each liquid, as the faster the marble rolls through the liquid, the less viscous the liquid is. In this case, I will create a table for my results, which will look somewhat like this:

With each trial, I will add the results, and find an average, which I will then create a graph to show my findings. Finding the average provides more reilable results.
