The graph of voltage (independent variable) vs current (dependent variable) should have voltage on the x-axis and current on the y-axis. The experimenter controls voltage and then measures current. You should use the best fit linear regression to find the best straight line fit for your data points. The slope will be delta amps/delta volts. If you rearrange Ohm's Law you will discover this slope is equal to 1/R. The independent direct measurement of the value of the resistor used will allow you to calculate a % error, which is a comparison of the value for R determined by the slope of your graph vs the direct measurement of resistance. % error = (direct measurement of R - slope R/ direct measurement of R) x 100 The video does not include the direct measurement of resistance, so use the value of 10.0 ohms as the direct measurement value (or accepted value).
