Set up a graph that shows voltage on the x axis and the number of paper clips picked up on the y axis.
When you graph anything your points are made up of an x value and a y value (x,y).
You’re going to use the voltage as your x value and the average number of paper clips picked up at that given voltage as your y value.
I’ll do the first one for you! For the 25-turn electromagnet at a voltage of 1.5V the average number of paper clips picked up was 6. Giving us the point (1.5,6) that’s what you should be graphing. Do the same for all of the others.
Comment if you need more clarification! I hope this helps!
