Remember to collect more data than you think you should need – or the instructor will have a fit ... make a graph. I don’t know why we always make a graph but it’s not a real physics ...

One of the most basic things students do in a physics ... the best way to analyze your data. You should also understand that a linear graph is nice because you can easily estimate a best fit ...

The 'line of best fit' is a line that goes roughly through the middle of all the scatter points on a graph. The closer the points are to the line of best fit the stronger the correlation is.
