H. Algebraically add the voltages recorded in the
"Positive Slope Measurement" column and enter the
total in the
·'Ey" space.
I. Multiply Ey by 45 (which is Ex, and enter the
result in the
ExEy space.
J. Multiply each
y value by the corresponding x value
and enter the result in the
"x Times y" column. Total
these values and enter the result in the
"Exy" space.
K. The equation for determining the "best fit
straight line" specification for each y value is:
y=mx+b
where m and b are constants to be calculated from data
previously taken.
NOTE
Calculate the values of m and b to at least 5
decimal places.
