*PLACE THIS AVERAGE IN THE DATA TABLE COMING WITH THE HAND OUT FOR
SLOPE OF REGRESSION. In that case, the Y -intercept of regression
line is not well defined (unless you compute average y intercept) and you
may leave the y- intercept box blank for the 10 ohm resistor.
ALSO, USE THIS AVERAGE IN THE PERCENT ERROR COMPUTATION OF ANALYSIS QUESTION
2, where you also compute the percent error between the 51 ohm label and the
actual resistor of around 51 ohms you measured once.
